Quick trip report from a Black Tusk ascent on March 15th. Snow conditions ranged from bullet proof down low to wind crust up high with variations of powder/sun affected in between. We began skinning about 2km up the switchback trail. Snow seemed stable, however there are large cornices on the tusk and col below it. Chimney is in good condition with plenty of stability for booting. Get after it while the skin track and boot pack are still in place! Thanks to the two guys who beat us to the punch in the morning and laid in the track, you're the real MVP. Pro tip: don't drive up to the lot regardless of how sweet you think your 4X4 is.
