The Middle Fork of the San Joaquin is now getting boated by one to several groups a year in most
years. It seems likely this incredible canyon will become steadily more popular.
More and more of the drops are being run, but many portages are still necessary. The famous Crucible section is often paddled now, so that big portage has been eliminated by some groups.
Season: This reach must be boated as flows drop near the very end of the run off
season. Often this will be in July. In wet years, the best boating levels could be in
Put-in elevation: 7,545 feet (2300 meters)
Take-out elevation: 3,330 feet (1,015 meters)+- (varies with elevation of Mammoth Pool)
Google Earth has excellent hi resolution aerial images of much of this section.
It is not legal to paddle within Devils Postpile itself, so hike boats downstream on the trail to the monument boundary before launching.
