Natural Avalanches Alex Lowe
Date
Activity
Snowboarding
From the ridge between Blackmore and Elephant we saw multiple natural large slab avalanches in the upper South Cotttonwood drainage. More natural avalanches not shown, mostly on northerly aspects. Appeared fairly recent and deep. Decided against skiing Alex Lowe and opted for good turns on Blackmore. Warm with moderate/strong southwest winds, minor transport.

Skiing
Skinned to the top of big Ellis completing 2 ECTs along the way. The first pit was at an elevation of 7946 feet, north of the burn, east aspect, exposed to the sky/not shaded. Snow depth 100cm. 2 buried crust layers, ECTNR. We did get the column to fracture below the lower crust layer by prying on it after the ECT test. The hardness of the faceted snow at the ground was 4 fingers trending to 1 finger. The second pit was completed at an elevation of 8209 feet, top of the burn, east aspect, exposed to the sky. Snow depth 120 cm, 2 buried crust layers, ECTNR. The column failed at the ground post ECT via the same prying as previous column. Hardness of the faceted snow at the ground was 4 fingers. We experienced no signs of instability during the day. The skiing was good. There were a few old ski tracks, partially buried by recent snow.

Notes
From obs on 03/07/2024: "Big slide below the radio tower. Kept our distance but looks like a large crown. The base up Portal is really inconsistent. Some spots it’s great and others you sink up to your chest. Had 4 instances of whompfing on fairly flat ground in the trees. 1st picture is from today and 2nd is from Sunday"
