"March 15 - 1924. Saturday Set off at 6.40 A.M. at [illegible] we are still in the H[illegible] county, but the mountains of eruptions are usually on or high here, but the plains are higher - about 4000 feet. The desert is here sandy and covered with very small dunes, some bunch grass, but mostly small greasewood, sage and stunted yuccas. In places there are [illegible] furs far away to the north. About 10 o'clock past El Paso we saw then / 2 were approaching the trail of the Rio Grande. had lands cut through the H[illegible] deposits. All is soft muddy yellowish sand with redclay and replete with granular grains of calcite. More than 100 feet I depth may be seen and all of it has grains of calcite. The Calcite mother-white. The bedding in plain is so regular and in the grain that it could be flag deposits. As one approach El Paso we appear to go through of the basalt, but it in light ochre color and is probably for sand crushed.
