 is a mountain park divided by a ridge into two portions. The surrounding mountains are not as high and abrupt as at but more rolling, and streams are small. Can jump across the two streams at   postoffisepost office [sic] now. The old lake beds so far as we saw them today are mere remnants of former more extensive beds, and contain many bands of volcanic ash and sand, the main portion of the beds, except in patches along the edges of the marginal hills, having been eroded away. Igneous dykes border the old lake basin at various places, but as yet see no  connection between these and the volcanic debris in the lake beds. I believe the igneous rocks are older.
