A note to whomever is doing Mt. Jefferson — Jefferson Notch Road is currently closed. There have been statements made that it may simply not reopen until next spring (it’s a road that always receives a lot of damage every year and requires repairs every spring anyway).
So if you were planning on the Caps Ridge trail, keep an eye on
http://www.fs.fed.us/r9/forests/white_mountain/conditions/roads_status.php
and be prepared to take an alternate route.
Some options:
Jewell Trail (best chance of trail having been cleaned up)
Castle Trail
Boundary Line Trail to JNR road walk to Caps Ridge Trail (least chance of trail having been cleaned up)
