Several natural avalanches hit highway 89 in Logan Canyon this morning and the road remains closed tonight due to continued avalanche threat. The avalanches we looked at were on slopes facing west and east, all below around 7000' in elevation.

Here are a few photos of some of the lower elevation avalanches: These of the Dugway below Temple Fork. The wet slab avalanche consisting of rain-soaked fresh snow crossed both lanes here with 4 or 5 feet of wet debris.

These are persistent or deep slabs in Beaver Canyon..... The slabs failed on depth hoar or weak sugary faceted snow in the basal layers of the snowpack, and cleaned out the entire season's worth of snow to the ground.

Here are a few more that didn't effect the highway, but could've been dangerous and all too easy to get to booby traps .... Also, most looked like wet slabs...
