As stated in the bottom line, the main concern if you venture into the backcountry will be early season/low snow cover hazards. Rocks, stumps, alders, etc. Below is a run down of snow depths vs. elevation:

1,000′ (Turnagain Pass road elevation): 0-3 inches
2,000′ (Treeline): 18″ to 2 feet
2,500′ (Top of Treeline): 2 feet
3,200′ (Above Treeline – Alpine): 3 feet

The good news is a very stout crust exists in the middle of the pack with strong melt-freeze snow below, which is covering up many of the smaller rocks (Photo above). More details from CNFAIC’s field day yesterday are HERE and HERE.

Wind Slab:
In high elevation extreme terrain, off ridgelines and peaks, there is the possibility of finding and triggering a wind slab. Watch for rounded stiff wind deposited snow that feels hollow. Also, be aware of what is below – cliffs/rocks – in the event even a small slab is triggered.

Loose Snow sluffs:
On steep slopes, 40 degrees and above, watch for sluffing in the settled snow from 11/22. Sluffs are expected to be low volume.

Weather

Thu, November 27th, 2014

Yesterday we saw broken cloud cover and valley fog obscure much of the mountainous terrain. Winds were light from the Northwest and temperatures were in the mid 20’s F above treeline.

Today, we can expect partly sunny skies with high clouds streaming in from the West. Ridgetop winds are expected to be light and variable. Temperatures have cooled off overnight and are expected to be in the teens near treeline and the low 20’sF on the ridgetops.

Tomorrow, Black Friday, we should see an increase in cloud cover, and possibly a flake or two, as rotating lows in the Bering move west and the associated frontal system begins to spill into Southcentral. This will continue to move our way and give us a chance for snow (to sea level!) Saturday and into Sunday.

Riding Areas

Updated Tue, June 01st, 2021

Status of riding areas across the Chugach NF is managed by the Glacier and Seward Ranger Districts, not avalanche center staff. Riding area information is posted as a public service to our users and updated based on snow depth and snow density to prevent resource damage at trailhead locations. Riding area questions contact: mailroom_r10_chugach@fs.fed.us
