Leaving the Mule Bridge trail head you'll pass Yellow Dog creek above in half an hour.

If hiking in forested areas is what you like then the Marble Mountain Wilderness is for you. Just south of the Oregon border, the Marble Mountain area is unlike the Sierras. There are areas of granite but you'll mostly find metavolcanic rock. Marble Mountain itself is marble that originated as a coral reefs in a tropical sea. There are several areas of granite with the Wooley Creek pluton being the largest followed by the English Peak pluton. Several smaller ones are scattered throughout the area. I didn't make it to the Wooley Creek area but if you do go I should point out one thing. The Forest Service brochure and comments at the trail head log book mention healthy specimens of Poison Oak as well as rattlesnakes. I can put up with the snakes but I think twice about the Poison Oak. I may have built up an immunity to it but I really don't want to check it. Snakes want to mess with me as much as I want to mess with them.

Because of a problem with my water filter I only spent a little time there but I'd like to go back. The major downfall, or is it windfall, is that its a long drive for most people. From Sacramento its 310 miles and 360 from San Francisco. It took me over 6 hours to drive there. If driving up from the south I recommend taking I-5 to Yreka and then heading southwest toward the wilderness. I came back by way of Weaverville and the difference in traffic was significant. Time wise it was about the same. Elevation in the wilderness varies from 3500 to 8300 feet. In the higher elevations you'll see more meadows and bare rock. Elevation at the trail heads can vary also. I didn't see too many people there but the register at the trail head indicates that most people that hike here are from the local area with some coming from all areas of the state. There are a lot of horse packers also. Some of the more popular lakes have pit toilets.
