Route & General Observations

Toured and skied Tincan off of the normal uptrack and in the trees to the north near the base of CFR. We encountered debris from a large avalanche (D2+, 2.5?) that looked like it had started at about the 2600 foot level and ran down to the approx. 1900 foot level. Debris ran a surprisingly long distance over low angle terrain. It is possible it could have started higher up on CFR but visibility was poor and the debris was getting covered in new snow. It is most likely the slide occurred the previous night since we did not observe it on the previous day.
