Something is broken on the Inyo N.F. website tonight. I am emailing them. This link is broken:   Permit Pickup Instructions

Here's what I did to pick up my permit for the Whitney Main Trail last week:

Send an email to: SM.FS.WildPmt_Inyo@usda.gov
Subject should have: Hike start date, Trailhead

Email body should:
give the reservation number
give the group size
For Mt Whitney, you should state that you have viewed the "Mt Whitney Leave No Trace Video"
Say how you will store your food.

When all else fails, call the Wilderness Permit Office: 760-873-2483   then press 0, then let it ring and ring until someone picks up. If it disconnects, repeat the process.
