This is a traverse hike going from the east end of Rattlesnake Mountain to the west end. We will meet at the west end (Grand Prospect trailhead) at 8am, then get into cars to carpool to the West end (Rattlesnake Ledge trail head) to start the hike. When we finish some one will need to volunteer to take the earlier carpool drivers back to their car. Let's all have fun and do a traverese!
8am at the Grand Prospect Trailhead.
