Traveled from Hurricane Ridge road about 1/4 mile beyond the Klahhane Ridge trailhead up to the intersection with the Switchback Trail, then generally followed the trail to the area West of the Mount Angeles summit. Shifted to crampons for a summit attempt. Elected to stop at 6250' elevation where the chute to the summit was loaded with much hollow sounding, wind-transported snow. Observed some whumping around 5200'-5500'. Frequently encountered 1-2" of newer wind-transported snow over ice/crust making skinning more difficult than typical. Ski crampons recommended for the trip up.
