[54] The divide between the waters of Green and Bear River may be crossed at several points. Its altitude is about eight thousand feet, and all travellers speak of the wide view. The mountains to the west are those of the Bear River range, running between the arms of the river, for which see our volume xxi, p. 199, note 44.--ED.

[55] The upper road from Green River, usually known as Sublette's road, comes across by way of Crow Creek, a branch of Ham's Fork, and Sublette Creek, a tributary of the Bear. Smith's Fork comes almost directly from the north, its headwaters nearly interlacing with Salt River branch of Lewis (or Snake) River. It enters Bear River quite near the dividing line between Wyoming and Idaho.--ED.

[56] The first crossing of Bear River is just above the mouth of Thomas's Fork. For a detailed map of this stretch of the road see Frémont's "Exploring Tour" (_op. cit._ in note 30), p. 132.--ED.

[57] The big hill is just beyond the bend of the Bear, below Thomas's Fork, and the nearest approach the road makes to the valley of Bear Lake. This lake is evidently the remains of one that occupied a much larger area, as the marshes at its upper end signify. It now measures about nineteen miles in length, with an average width of six, and a depth of from forty to sixty feet. The lower portion of the lake is in Utah and the upper in Idaho. Its waters are noted for their exquisite blue tint.--ED.

[58] For the location of these springs see our volume xxi, p. 200, note 45.--ED.

[59] A map of these springs can be found in Frémont's "Exploring Tour" (_op. cit._ in note 30), p. 135. Steamboat Spring is a miniature geyser, an analysis of whose waters is given by Frémont, p. 136.--ED.

[60] For a brief note on Salt Lake see our volume xxi, p. 199, note 44.--ED.

[61] The entire route from Soda Springs at the bend of Bear River to Fort Hall was about fifty miles in length, crossing the basaltic, volcanic plateau which Palmer describes, to the waters of Portneuf River, down which the trail passed to Fort Hall. For the founding of this post see Townsend's _Narrative_, in our volume xxi, pp. 209-211.--ED.

[62] Captain James Grant was Hudson's Bay factor in charge at Fort Hall for several years during the immigration movement. Most of the travellers speak of his courtesy and readiness to assist. He was at this post in 1842, when Matthieu describes him as a large man, resembling Dr. McLoughlin--_Oregon Historical Quarterly_, i, p. 84. He seems to have later settled in Oregon.--ED.
