Here are a few more pictures from our ride today. Nothing special, about 60 minutes, walking through 2' of snow. I rode Brego out on his loose ring snaffle and he was perfect. He really is a "save my butt" kind of trail horse. I trust him.
View of the glacial boulder. Standing about 20' away.
Better view. The top is at mid height in this picture.
The water trough is the little black hole in the sea of snow. The spring is still running though and no external heater required. Yet.
