The Rampart Ridge loop (Rampart Ridge plus Wonderland Trail back to Longmire) is in good shape. A few snow patches on the flattish stretch between the Rampart Ridge overlook (of Longmire) and the Wonderland, but nothing at all difficult to cross (the trail is always easily visible on the other side); snow coverage less than 5% on this section. Essentially no snow on the route elsewhere. We did investigate the Wonderland from the Rampart Ridge / Wonderland junction down toward Kautz Creek. Little snow for the first 100 yards, then increasing amounts, with the "flat" at 3650' almost 100% covered. Probably best not to attempt to go all the way to Kautz Creek unless you know the trail (or have a good sense of how trail builders route trails).
Carter Falls Trail (the Wonderland east from Cougar Rock to the Falls) is in excellent shape, with no snow or other problems.
