>>984322The House Range is nice but a little far (3 hrs) Marjum Canyon and Ibex have A+ camping. Newfoundland Mountains are on my hit list. Lots of spots in Skull Valley can be nice and remote. Go drive out on Promontory Point and explore.
There are some fantastic hot springs out by Wells, NV and good camping in the Toano Range and near Pequop, NV. Goshute Range has a hawk watching station.
Generally I go to southern Utah this time of year and drive a little farther to get the good stuff. Northern Utah is still cold and snowy by and large.
