Show 1& 2 SAND- FLATS- NORTH END OF Trf « LAfcfl. to the northward, probablyto the more favoured region of the Pan-nack and the Port Neuf. : The shore party did not reach camp until nearly ten 6' clock to- night, having been obliged to cross the extensive flat, some six or eight milfes wide, after the termination of a day's work of seven miles of chain- line. - They describe the country over . which they have passed to- day as a mud- flat, studded with Might elevations, like islands, six or eight* feet high, and cOverfed with grease- wood and artemisia. One single stream was passed, four feet wide and one in depth, with gravelly bottom, the water of which was drinkable. The rest was one . barren, dreary waste, ove* which the water of the lake had at one time flowed, and its gradual recession had left behind it nothing but solitude and desolation. . Tuesday, May 14.- Engaged all this day in erecting two tri-angulation stations-; one upon a projecting peak west of ^ Turret Rock, and another upon a high rocky cliff, about a mile north < tf the camp. As no timber « 6uld be obtained within twenty miles, both of these stations were constructed wholly of stone, laid np in* a . conical form, upon the highest point of their respective peaks, and covered with " white cottoq. This was a work of great labour, as the stone was difficult to be obtained, and had to be' laid with great care to enable the station to resist the force of the violent / winds to which it would be exposed. I added to- day the accomplishment of laying stone- wall to my numerous other avocations, and returned* to camp thoroughly wearied, and with the skin of my hands nearly worn thorough. The rock upon which the higher station was ferected is part, of a ridge coming from the north, and terminating at this point in a bold, rugged escarpment, commanding an extensive view to the southward and westward. It consisted of a light- gray limestone, very friable, and rapidly disintegrating. The roclra m the vicinity are completely covered over with a casing of tufa, which has formed upon them, adapting itself to all their irregularities. It is very hju- d, and as the limestone underneath is constantly crumbling away from it, numerous caves are forming,' the roof and sides of which consist of the tufa alone. . The covering is from four to six inches thick. In one spot I found the rock for a small space thinly veneered with jade. Some broken specimens of Indian pottery were found at this camp, and also tome pieces of obsidiab. The latter, probably, had been procured elsewhere by the Savages, for makirtg arrow- heads: |
