We drove both of these passes last week. Tomichi is a great run beginning from Whitepine in the trees, going through a few creek crossings, then gaining elevation on a shelf road to the top of the pass. There is a great view of the southside of Hancock pass and the Brittle Silver basin from the top of Tomichi Pass. The northside of Tomichi Pass decending into the basin is a very narrow shelf road in which passing is impossible the whole way. Be sure that no one is coming up as you are going down. At the bottom of the Basin, there is an open mine that is great to explore. It goes in pretty far and divides into three horizontal shafts and still has the ore cart rails inside. The southside of Hancock Pass is easy and fun with lots of smooth areas of travel. The northside of Hancock Pass is very rocky and progress will be quite slow. You can do both passes with your Jeep.
