Sept 11. Day chilly & bleak. Small showers in the afternoon. Camped before dark at Goose Lake. Rode on with Ashe from lunching place to look at sections in escarpment overlooking the great clay & cactus plain. E. of E. Fork. (see notes July 14)

Geol. The lowest beds seen, near the foot of the slopes in coulÈs N of line. Greyish & brownish sandy-clays &c overlying these a very conspicuous red layer which on examination found to be red sandstones & shales baked by the combustion of a lignite. The latter found in place in the locality but not exposed so as to enable examination of its character or thickness. Some of the baked beds show obscure impressions of plants. Some clays seem to have held no iron & are white & resemble firebrick, other layers have been completely porcelanised by semi-fusion. Overlying the red beds whitish & yellowish sandy clays. Section no doubt near base of Lig. Tert. & very probably on same horizon as the part of the section showing red beds in the Bad lands. E. of Woody Mt Astron. Station.

The edge of the lignite plateau about 15 m. N. of the line comes within about 3 m. of Meridian passing through crossing of E. Fork & trail.
