"Guide to the Theodore Solomons Trail" by Dennis Gagnon, Western Tanager Press, 1987, ISBN: 0-934136-34-3.
The TST is a lower elevation alternate to the JMT which stays within the bounds of the timberbelt of the Middle Sierra.
An older forum post said: "Going south from Clover Meadow just outside the Ansel Adams Wilderness, the trail has been abandoned for 10 years. Dropping into and climbing out of the San Joaquin River Canyon is an exercise in route-finding. The best part is the solid bridge over the river. The trail south of the river is almost as bad."
Parts of the "trail" could exist only on a map these days.
