EXPLORATIONS FROM A. D. 1852 To A.D. 1851. 15 
' Messrs. Beale and Heap passed over nearly this same route in advance of Captain Gunnison’ s 
party on their way to California. The journey of these enterprising travellers was a very 
trying one; and they lost nearly everything they had in attempting to cross Grand river on a 
raft during a high stage of water. They published a brief and interesting narrative of their 
journey, accompanied by a map. 
Colonel J. C. Frémont* also passed over nisl this same route «sides the winter of 1853-54, 
He crossed the Sierra Blanca through the Sandy Hill Pass; thence his route was not materially 
different from Captain Gunnison's to the point where the latter left Grand river. Colonel 
Frémont continued further south, and crossed the Sawatch mountains south of Gunnison's route. 
He had with him, as far as the Mormon settlement, Mr. F. W. Egloffstein, as topographer. 
SURVEY FOR A RAILROAD TO THE PACIFIC NEAR THE 41sr PARALLEL, BY LIEUTENANT E. G. BECK WITH, 
1854. 
The report of this route, by Lieutenant Beckwith, forms part of Volume II of the quarto edition 
of the Pacific Railroad Reports. The topographical maps are in four sheets, on a scale of twelve 
miles to an inch. The profiles are drawn on a horizontal scale of 16 miles to an inch, the 
vertical scale being 28755 times larger. This report of Captain Beckwith was also published 
in House Document No. 129, 1st session 33d Congress, and was accompanied by a preliminary 
map on a scale of 50 miles to an inch. 
On the 3d of April Lieut. E. G. Beckwith, aided by Mr. F. W. Egloffstein and the surviving 
assistants of Captain Gunnison, started to examine the practicability of the Wasatch mountains 
east of Great Salt lake. Leaving Salt Lake city, they travelled up the eastern shore of the 
lake, to the cafion of Weber's river, passed up this stream to White Clay creek, crossed the 
divide between it and Bear river, travelled along the heads of Muddy creek and Black’s Fork, 
to Henry's Fork of Green river, and then followed down this stream nearly to its mouth. 
Retracing their steps to the divide between Muddy and Bear rivers, they attempted to dis- 
cover a route to the Kamas prairie and Timpanogos river, more direct than the one by White 
Clay creek and Weber's river. This they were unable to do, being deterred as much by snow 
as by the rugged aspect of the country. Descending White Clay creek to Weber's river, they 
followed the latter stream to where it turns east into the Uintah mountains; thence crossing the 
dividing ridge they reached — river, examined its — to m "id and thence 
returned to Salt Lake city. 
On the 5th of May the expedition, under Lieut. Beckwith, left Salt AN city under instruc- 
tions to explore a route ‘‘south of Great Salt lake in the direction of the ‘Sink’ of Humboldt s 
or Mary's river, thence towards Mud lake, and across to the tributaries of Feather river, and 
thence by the most practicable route to the valley of the Sacramento." Leaving the city, they 
crossed the Jordan river, passed around the northern end of the Oquirrh mountains, entered 
the Tuilla valley, and doubling the northern end of an intervening range of mountains, entered 
Spring or Lone Rock valley. 
Proceeding southwesterly they passed the Cedar and the Pi-ja-ro-ja-bi mountains. Passing 
this range they continued the exploration westward to a pass in the Wa-ro-ja mountains, by 
which they entered Franklin valley. They then travelled southward down this valley, along 
the eastern face of the Humboldt mountains, for twenty or thirty miles, where they turned west- 
ward, crossed the mountains through the Hastings Road Pass, and struck the head of the south
