The southeast end of the Chiricahua Peak Trail is formally decommissioned and is not part of the trail system anymore. It is occasionally unofficially maintained but is not in the system. It was removed from USFS maps at least a decade ago, and has deliberately lacked signage while other junctions around it have remained signed in that time. It might be a candidate for informal = yes.

The Aspen Trail does not even have evidence on the ground of existing anymore despite multiple serious attempts to find it from multiple people, including formally by the USFS, over the last decade.

What's with all the deleted roads? There are tons of legitimate Forest Roads that got deleted in this changeset, including the Deer Creek TH road, FR 201 to Mt. Peeley, FR 25 to Mormon Grove, and more.
