Following the Lava Beds and Tule Lake, CA, we headed into northwest Nevada. Up and over a couple smaller mountain range passes through Alturas and Cedarville CA on route 299. In Cedarville there is a BLM office with friendly folks, worth stopping there for info and route information.
Once into Nevada it's all desert gravel roads. Route 34 along the west edge of the Black Rock Desert was pretty smooth for gravel, not very washboardy.
We camped near the mouth of the Little High Rock Canyon, in the picture below looking south, the valley drains into a small nearly dry lake bed. The small lake bed was nearly dry, but was still wet enough for an egret to be there and a few other birds. The trail back a couple miles near the canyon from 34 was slow going and dusty. The area to the north is wilderness and no vehicles are allowed.
We had done our laundry earlier in Alturas, so we got it hung out to dry right away. Everything dried real fast, and it may have helped cool us off a little too.
I scouted further up the trail on my bike the afternoon that we got there. About 2 miles further back is the mouth of the Little High Rock Canyon. The creek has some wet spots, and especially at the mouth there are many cliff swallows gliding around eating bugs and building nests.
The next morning, we all rode our bikes up to the canyon, and hiked in a couple miles. There was a pretty good trail at first, but it mostly disappeared after a mile or two. The canyon may be around 10 miles, before it comes out the other side to High Rock lake.
After two nights, we went down through Gerlach to the south, and then the gravel roads to the east, through Sulfur, NV. Not much there, big sulfur mine though. If we go this way again, I'd go straight across the Black Rock playa, avoiding most of the pretty poor gravel road, route 48, from Gerlach towards Sulfur.
To the east of Sulfur is another smaller lake bed, 2-3 miles across. We stopped for lunch, and continued on. It was weird driving on this one, maybe seeing the edges not so far away, it felt like we were on ice and it might fall through.
