Santa Rosa Mtns. Humboldt Co., Nevada July 28-30 Arvey Journal July 30 Trees. Very dry and windy here. Martin Creek runs through here and it is fair sized but warm. (Saw hot springs upstream). Martin Creek heads in Santa Rosa Mtns. near the ranger station but winds down the back side (SW) and ends up on this side by (NE) by coming through a narrow gap here. Got up early and hiked upstream, collecting, about 2 1/2 miles. Large Volcanic cliffs cap the hillsides here and form cliffs. The hillside leading up to them are covered with Artemisia.

Up about to the SW stands Granite Peak, 10970' and a ridge of lesser peaks. Snow still stands in some of its crags areas. The snow patches are not very extensive (and this
