Chapter 5

Cavate lodges comprise a type of structures closely related to cliff houses and cave dwellings. The term is a comparatively new one, and the structures themselves are not widely known. They differ from the cliff houses and cave dwellings principally in the fact that the rooms are hollowed out of cliffs and hills by human agency, being cut out of soft rock, while the former habitations are simple, ordinary structures built for various reasons within a cove or on a bench in the cliffs or within a cave. The difference is principally if not wholly the result of a different physical environment, i.e., cavate lodges and cave dwellings are only different phases of the same thing; but for the present at least the name will be used and the cavate lodges will be treated as a separate class.

There are but three regions in the United States in which cavate lodges are known to occur in considerable numbers, viz, on San Juan river, near its mouth; on the western side of the Rio Grande near the pueblo of Santa Clara; and on the eastern slope of San Francisco mountain, near Flagstaff, Arizona. To these may now be added the middle Verde region, from the East Verde to a point north of Verde, Arizona.

Within the middle Verde region there are thousands of cavate lodges, sometimes in clusters of two or three, oftener in small groups, and sometimes in large groups comprising several hundred rooms. One of these large groups, located some 8 miles south of Verde on the eastern side of the river, has been selected for illustration.

The bottom lands of the Rio Verde in the vicinity of Verde have been already described, and the cavate lodges in question occur just below the southern end of this large area of tillable land, and some of them overlook it. The river at this point flows southward, and extending toward the east are two little canyons which meet on its bank. North and south of the mouth of the canyons the bank of the river is formed by an inaccessible bluff 180 or 200 feet high. These bluffs are washed by the Verde during high water, though there is evidence that up to a recent time there was a considerable area of bottom land between the river and the foot of the bluff. Plate XXIV shows the northern end of the group from a low mesa on the opposite side of the river; the eastern bank of the river can be seen in the foreground, while the sandy area extending to the foot of the bluff is the present high-water channel of the Verde. The map (plate XXV) shows the distribution of the cavate lodges composing the group, and plate XXVI shows the character of the site. The cavate lodges occur on two distinct levels--the first, which comprises nearly all the cavate lodges, is at the top of the slopes of talus and about 75 feet above the river; the second is set back from 80 to 150 feet from the first tier horizontally and 30 or 40 feet above it. The cavate lodges occur only in the face of the bluff along the river and in the lower parts of the two little canyons before mentioned. These canyons run back into the mesa seen in the illustration, which in turn forms part of the foothills rising into the range of mountains hemming in the Rio Verde on the east.

The walls of the canyon in the cavate-lodge area are composed of three distinct strata, clearly defined and well marked. The relations of the strata, at points on the northern and western sides of the north canyon, are shown in figure 289 and plate XXVI. The lowest stratum shown in the figure is that in which almost all the cavate lodges occur. It is about 8 feet thick and composed of a soft, very friable, purple-gray sandstone. Above it lies a greenish-white bed a few inches thick, followed by a stratum of a pronounced white, about 12 feet thick. This heavy stratum is composed of calcareous clay, and the green bed of a calcareous clay with a mixture of sand. The white stratum is divided at two-thirds its height by a thin belt of greenish-white rock, and above it there is another belt of purple-gray sandstone about 12 feet thick. The top of this sandstone forms the ground surface south of the point shown in the diagram, while on the north and east it forms the floor of the upper tier of cavate lodges.

On the southern side of the canyon the lower purple stratum shows three distinct substrata; the upper is reddish purple and about 3½ feet thick, the middle is purple gray, about 7 feet thick, and apparently softer than the upper and lower strata. The lodges occur in the middle purple substratum, their floors composed of the upper surface of the lower stratum and their roofs of the under surface of the upper stratum. Those on the north side are similarly placed, their roofs being about 3 feet below the white, except that in several instances the upper part of the purple up to the white has fallen, making the cavity larger. This has occurred, however, since the abandonment of the caves, and the debris, still fresh looking, is in situ.

The formation in which the lodges occur is not of volcanic origin, although the beds composing it were perhaps deposited by hot springs during the period of great volcanic activity which produced San Francisco mountain in central Arizona and the great lava flows south of it. In view of the uncertainty on this point and the further fact that almost all the cavate lodges heretofore found were excavated in tufa, ash, or other soft volcanic deposits, the report of Mr. Joseph S. Diller, petrographer of the U.S. Geological Survey, will be of interest. It is as follows:

The coarse-grained specimen is sandstone, that of medium grain is argillaceous sandstone, and the fine-grained one is calcareous clay. The coarse-grained friable sandstone, in which the lodges have been excavated, consists chiefly of subangular and rounded grains of quartz and feldspar with a small proportion of black particles. Many of the latter are magnetite, while the others are hornblende and various ferromagnesian silicates. I did not detect any fragments of volcanic origin.

The specimen of argillaceous sandstone is made up of thin layers of fine-grained sand of the same sort as the first, alternating with others containing considerable clay. In the clay layers, a trace of carbonate of lime was found here and there, forming a transition of the calcareous clay.

The calcareous clay when placed in acid effervesces vigorously, but when allowed to stand the effervescence ceases in a few minutes and the insoluble white clay remains.

All the strata composing this formation are very soft; the purple-gray material of the middle layer is so soft that its surface can be rubbed off with the hand. They are also minutely stratified or laminated, and the laminæ are not well cemented together, so that a blow on the roof of a cavity with a stone or other implement will bring off slabs varying from half an inch to an inch and a half in thickness. These thin strata or laminæ are of unequal hardness, weathering in places several inches into the face of the rock in thin streaks of a few inches or less. The middle purple stratum exhibits this quality somewhat more decidedly than the others, and this fact has doubtless determined the selection of this stratum for the location of the lodges, as a room can be excavated in it more easily than a room of a similar size could be built up with loose rock.

The almost absolute dependence of the native builder on nature as he found it is well illustrated by these cavate lodges. At a point in the northern wall of the northernmost canyon, shown in the diagram (figure 289) and in plate XXVI, there is a small fault with a throw of about 2½ feet, and the floors of the lodges west of the fault are just that much lower than the floors east of it. Furthermore, where the purple-gray stratum in which the lodges occur is covered up by the rising ground surface, the cavate lodges abruptly cease. In the northern and southern ends of the group the talus encroaches on and partly covers the purple-gray stratum, and in these places the talus has been removed from the face of the rock to permit the excavation of lodges. In short, the occurrence of the cavate lodges in this locality is determined absolutely by the occurrence of one particular stratum, and when that stratum disappears the lodges disappear. So far as can be ascertained without actually excavating a room there is no apparent difference between the stratum in which the lodges occur and the other purple strata above and below it. That there is some difference is indicated by the confinement of the lodges to that particular level, but that the difference is very slight is shown by the occurrence in two places of lodges just above the principal tier, a kind of second-story lodge, as it were. It is such differences in environment as these, however, often so slight as to be readily overlooked, which determine some of the largest operations carried on by the native builders, even to the building of some of the great many-storied pueblos, and, stranger still, sometimes leading to their complete abandonment.

In the region under discussion cavate lodges usually occur in connection with and subordinate to village ruins, and range in number from two or three rooms to clusters of considerable size. Here, however, the cavate lodge is the feature which has been most developed, and it is noteworthy that the village ruins that occur in connection with them are small and unimportant and occupy a subordinate position.

There are remains of two villages connected with the cavate lodges just described, perched on the points of the promontories which form the mouths of the two canyons before mentioned. The location of these ruins is shown in plate XXV. The one on the southern promontory is of greater extent than that on the northern point, and both are now much broken down, no standing wall remaining. A general view of the ruin on the northern promontory is given in plate XXVII, and the same illustration shows the remains of the other village on the flat top of the promontory in the farther part of the foreground.

The cavate lodges are generally rudely circular in shape, sometimes oblong, but never rectangular. The largest are 25 and even 30 feet in diameter, and from this size range down to 5 or 6 feet and thence down to little cubby-holes or storage cists. Owing to their similarity, particularly in point of size, it is difficult to draw a line between small rooms and large storage cists, but including the latter there are two hundred rooms on the main level, divided into seventy-four distinct and separate sets. These sets comprise from one to fourteen rooms each. On the upper level there are fifty-six rooms, divided into twenty-four sets, making a total of two hundred and fifty-six rooms. As nearly as can be determined by the extent of these ruins the population of the settlement was probably between one hundred and fifty and two hundred persons.

There is great variety in the rooms, both in size and arrangement. As a rule each set or cluster of rooms consists of a large apartment, entered by a narrow passageway from the face of the bluff, and a number of smaller rooms connected with it by narrow doorways or short passages and having no outlet except through the large apartment. As a rule two or more of these smaller back rooms are attached to the main apartment, and sometimes the back rooms have still smaller rooms attached to them. In several cases there are three rooms in a series or row extending back into the rock, and in one instance (at the point marked _E_ on the map, plate XXV) there are four such rooms, all of good size.

Attached to the main apartment, and sometimes also to the back rooms, there are usually a number of storage cists, differing from the smaller rooms of the cluster only in size. These cists or cubby-holes range in size from a foot to 5 feet in diameter, and are nearly always on a level of the floor, although in some instances they extend below it. Storage cists are also sometimes excavated in the exterior walls of the cliffs, and occasionally they are partly excavated and partly inclosed by a rough, semicircular wall. An example of the latter type is shown in figure 290.

As a rule the cavate lodges are set back slightly from the face of the bluff and connected with it by a narrow passageway. Another type, however, and one not uncommon, has no connecting passageway, but instead opens out to the air by a cove or nook in the bluff. This cove was used as the main room and the back rooms opened into it in the usual way by passageways. A number of lodges of this type can be seen in the eastern side of the northern promontory or bluff. Possibly lodges of this type were walled in front, although walled fronts are here exceptional, and some of them at least have been produced by the falling off of the rock above the doorway. The expedient of walling up the front of a shallow cavity, commonly practiced in the San Juan region, while comparatively rare in this vicinity, was known to the dwellers in these cavate lodges. At several points remains of front walls can be seen, and in two instances front walls remain in place. The masonry, however, is in all cases very rough, of the same type as that shown in plate XXVIII.

In this connection a comparison with the cavate ledges found in other regions will be of interest. In 1875 Mr. W. H. Holmes, then connected with the Hayden survey, visited a number of cavate lodges on the Rio San Juan and some of its tributaries. Several groups are illustrated in his report.[5] Two of his illustrations, showing, respectively, the open front and walled front lodges, are reproduced in plates XXIX and XXX. The open front lodges are thus described:

I observed, in approaching from above, that a ruined tower stood near the brink of the cliff, at a point where it curves outward toward the river, and in studying it with my glass detected a number of cave-like openings in the cliff face about halfway up. On examination, I found them to have been shaped by the hand of man, but so weathered out and changed by the slow process of atmospheric erosion that the evidences of art were almost obliterated.

The openings are arched irregularly above, and generally quite shallow, being governed very much in contour and depth by the quality of the rock. The work of excavation has not been an extremely great one, even with the imperfect implements that must have been used, as the shale is for the most part soft and friable.

A hard stratum served as a floor, and projecting in many places made a narrow platform by which the inhabitants were enabled to pass along from one house to another.

Small fragments of mortar still adhered to the firmer parts of the walls, from which it is inferred that they were at one time plastered. It is also extremely probable that they were walled up in front and furnished with doors and windows, yet no fragment of wall has been preserved. Indeed, so great has been the erosion that many of the caves have been almost obliterated, and are now not deep enough to give shelter to a bird or bat.

[Footnote 5: Tenth Ann Rep. U.S. Geol. Survey, 1876, pp. 288-391.]

Walled fronts, the author states, were observed frequently on the Rio Mancos, where there are many well-preserved specimens. He described a large group situated on that stream, about 10 miles above its mouth, as follows:

The walls were in many places quite well preserved and new looking, while all about, high and low, were others in all stages of decay. In one place in particular, a picturesque outstanding promontory has been full of dwellings, literally honeycombed by this earth-burrowing race, and as one from below views the ragged, window-pierced crags [see plate XXX] he is unconsciously led to wonder if they are not the ruins of some ancient castle, behind whose moldering walls are hidden the dread secrets of a long-forgotten people; but a nearer approach quickly dispels such fancies, for the windows prove to be only the doorways to shallow and irregular apartments, hardly sufficiently commodious for a race of pigmies. Neither the outer openings nor the apertures that communicate between the caves are large enough to allow a person of large stature to pass, and one is led to suspect that these nests were not the dwellings proper of these people, but occasional resorts for women and children, and that the somewhat extensive ruins in the valley below were their ordinary dwelling places.

It will be noticed that in both these cases there are associated ruins on the mesa top above, and in both instances these associated ruins are subordinate to the cavate lodges, in this respect resembling the lodges on the Verde already described. This condition, however, is not the usual one; in the great majority of cases the cavate lodges are subordinate to the associated ruins, standing to them in the relation of outlying agricultural shelters. Unless this fact is constantly borne in mind it is easy to exaggerate the importance of the cavate lodges as compared with the village ruins with which they are connected.

The cavate lodges near San Francisco mountain in Arizona were visited in 1883 by Col. James Stevenson, of the Bureau of Ethnology, and in 1885 by Maj. J. W. Powell. Major Powell[6] describes a number of groups in the vicinity of Flagstaff. Of one group, situated on a cinder cone about 12 miles east of San Francisco peak, he says:

Here the cinders are soft and friable, and the cone is a prettily shaped dome. On the southern slope there are excavations into the indurated and coherent cinder mass, constituting chambers, often 10 or 12 feet in diameter and 6 to 10 feet in height. The chambers are of irregular shape, and occasionally a larger central chamber forms a kind of vestibule to several smaller ones gathered about it. The smaller chambers are sometimes at the same altitude as the central or principal one, and sometimes at a lower altitude. About one hundred and fifty of these chambers have been excavated. Most of them are now partly filled by the caving in of the walls and ceilings, but some of them are yet in a good state of preservation. In these chambers, and about them on the summit and sides of the cinder cone, many stone implements were found, especially metates. Some bone implements also were discovered. At the very summit of the little cone there is a plaza, inclosed by a rude wall made of volcanic cinders, the floor of which was carefully leveled. The plaza is about 45 by 75 feet in area. Here the people lived in underground houses--chambers hewn from the friable volcanic cinders. Before them, to the south, west, and north, stretched beautiful valleys, beyond which volcanic cones are seen rising amid pine forests. The people probably cultivated patches of ground in the low valleys.

About 18 miles still farther to the east of San Francisco mountain, another ruined village was discovered, built about the crater of a volcanic cone. This volcanic peak is of much greater magnitude. The crater opens to the eastward. On the south many stone dwellings have been built of the basaltic and cinder-like rooks. Between the ridge on the south and another on the northwest there is a low saddle in which other buildings have been erected, and in which a great plaza was found, much like the one previously described. But the most interesting part of this village was on the cliff which rose on the northwest side of the crater. In this cliff are many natural caves, and the caves themselves were utilized as dwellings by inclosing them in front with walls made of volcanic rocks and cinders. These cliff dwellings are placed tier above tier, in a very irregular way. In many cases natural caves were thus utilized; in other cases cavate chambers were made; that is, chambers have been excavated in the friable cinders. On the very summit of the ridge stone buildings were erected, so that this village was in part a cliff village, in part cavate, and in part the ordinary stone pueblo. The valley below, especially to the southward, was probably occupied by their gardens. In the chambers among the overhanging cliffs a great many interesting relics were found, of stone, bone, and wood, and many potsherds.

[Footnote 6: Seventh Ann. Rep. Bur. Eth., 1891, p. xix.]

It will be seen that the first group described bears a remarkably close resemblance to the cavate lodges on the Rio Verde. The lodges themselves are smaller, but the arrangement of main apartment and attached back rooms is quite similar. It will be noticed also that in the second group described village ruins are again associated on the summit of the cliff or ridge. Major Powell ascertained that these cavate lodges were occupied by the Havasupai Indians now living in Cataract canyon, who are closely related to the Walapai, and who, it is said, were driven from this region by the Spaniards.

The cavate lodges on the Rio Grande, in New Mexico, in the vicinity of the modern pueblo of Santa Clara, were also visited in 1885 by Major Powell and are thus described by him:[7]
