- Mt Patterson, the highpoint of the Sweetwater Range, was named possibly for James H. Patterson, a native of Ohio who settled in nearby Big Meadows around 1867.
- In June of 2014, the roads were open in their entirety. There was evidence that some had driven the entire distance to the summit.
- The map shows my route (in red) minus my side trip to Wheeler. One's starting point may be determined by either how willing you are to hike vs. the condition of the road, or where the best place to camp is to be found.
- One interpretation of the B route is shown in Blue.
- Camping spots may be found in several places. One spot suitable for multiple vehicles is found at the intersec- tion of the two roads, 32115 and 32116. See the location of the red dot on the map below.
