The entrance to the Slot on past Monday was an unparalleled disaster. Absurd sized bumps, carved out and frozen.the "Heidi trees" are the proper Red Dog Ridge, the one you refer to is the ridge above the East Face/Three Trees area. These are usually some of the nastiest bumps at Squaw (rivaled only those by the Slot entrance),
I'm lucky to survive ! Headwall & Sun Bowl were good. Entrance traverse to slot has probably melted now which,thankfully, saves us !
