Oh, by the way, did we forget to mention that Mike got knocked off his horse on the way coming back down from Minaret Lake?
It happened when Hank (the horse) went underneath a protruding unnoticed-by-Mike snag. Suddenly spying the branch, Mike attempted to avoid it by doing a kind of Keanu Reeves Matrix lay-back maneuver. It almost worked! Alas, Mike's helmet brim caught on the snag and Mike was pulled backwards off the horse, suddenly finding himself flat on his back staring up at the sky.
He was able to get up unaided and after a few minutes rest, was able to do some rudimentary nightclub two-step moves. The remainder of the ride back to the stable was uneventful, thank goodness.
