I put together a composite scan of the topographical maps for most of Northern Yosemite above Tenaya Lake. Below you’ll find a link to the resulting very large 8MB+ JPEG file image.
The file takes a while to load even on cable broadband. If you’re on dialup, this is the sort of file that you download exactly once and then refer to locally on your hard drive.
Contents (USGS 15-minute series):
- Matterhorn Peak quadrangle
- western half of Tower Peak quadrangle
- northern half of Tuolumne Meadows quadrangle
My Trails: several 1970’s hike routes are highlighted in yellow. There are some mistakes in tracing my routes. There is also a dogleg where I hiked about 3 miles up Virignia Canyon in the wrong direction.
- Matterhorn Peak 1972: the 9-day central loop from Tuolumne Meadows, to Matterhorn Peak, to Benson Lake and Pate Valley, returning via John Muir Gorge to Tuolumne Meadows
- Matterhorn Peak 1979: from Summit Lake down Virginia Canyon to Miller Lake and no further (long layover)
- Green Lake, Barney Lake and some other shorter hikes
Scan Issues: Scans were done on one of those “all-in-one” printer scanners with an 8-1/2×11 flatbed scan table and non-removable lid. Even with pieces aligned to within 1/10 degree, there were problems fitting the pieces together. Not all topo maps are published with consistent color values. In most cases, seams still match within 1/32 inch.
