Surface Hoar-What’s That???

WOW!!! 4 FEET OF SNOW, PAST 4 DAYS!!! GATE IS CLOSED AT MCBRIDE SPRINGS ON EVERETT MEMORIAL HIGHWAY &

MORE TO COME!!!

Gate is still closed at McBride Springs as of 12-23-10. Road is plowed up Castle Lake Road.

UPDATE-from Avalanche Advisory 12-22-10

We received a report this afternoon of a large natural avalanche on Gray Butte with a 5 ft. crown. The exact location and aspect were not clear, but I would guess it was on the open NW aspect which was wind loaded yesterday by SSE winds. Please call in (or post) your observations – it could save a life! 530-926-9614 County is working on the Everitt Hwy to Bunny Flat – stay tuned!

Update Wednesday, December 22, 8 am: We received 14-17 inches of snow during the last 24 hours on Mt. Shasta with water content of 1.66 in.  Castle Lake shows around 14 inches with less on Mt. Eddy.  Winds were not strong, but steady and mostly from the SSE, moving to the SW and WSW this morning.  Storm totals are 4-5 ft. of snow in the surrounding mountains.  Some natural avalanches may have occurred last night during the heaviest snow fall.  Human triggered avalanches could be possible today, especially if the sun peeks out, on all aspects below tree line where slope angles are 35 degrees or more.  Above tree line, northerly and easterly aspects are wind loaded and large wind slabs exist – avoid these areas and their run-outs.

My Favorite Holiday Tree

These trees are the famous Shasta Red Fir found on the upper slopes of Mt. Shasta. They were discovered by John Gill Lemmon who climbed to the summit of Shasta in 1879 and later named the tree he found upon the mountain’s slopes.

Surface Hoar~Feathery Crystals

The big concern is when new snow covers this layer “Surface Hoar”

. Faceted, corn-flake shaped snow crystals that are a type of frost that forms on the surface of the snow pack on cold, clear, calm nights.

Remember the avalanche essentials- Tranceiver, probe, shovel and most importantly “Your Avalanche Eyeballs”

Champagne Snow

This is what we call “Sugary” Snow! It’s fantastic to ski. This can also become a weak layer in the snowpack. Check weather forecast-

Looks like more snow is on the way dropping down into town. Maybe we’ll have a white Christmas after all.

I’ll be posting mountain road conditions throughout the holidays!

Have a great weekend!
