Thursday, 23rd. We could see no termination to the valley, not any signs of Mary’s river. We therefore concluded that we were too far south, and passed over the mountains to the north, where we struck a small stream running towards the N.W. On this we encamped and found plenty of grass, a few fish were caught, some of which were trout, which led us to the conclusion that this was a branch of Mary’s river. Distance 18 miles.
Yay! They have found a creek that will lead them to the south fork of Mary’s River (the Humboldt River). At last they are headed in the right direction. They passed over the Ruby Mountains at Harrison Pass. You can see the South Fork directly below Elko on this map.
