Danger Rose Tutorial
|
The danger level remains LOW (or Level 1) in the backcountry around Logan. Avalanches are generally unlikely, but recent drifting created a few pockets of (level 2) or MODERATE danger in exposed upper elevation terrain. Shallow snow conditions exist dictating a conservative and slow approach. |

CURRENT CONDITIONS |
|
It looks like a couple more inches of light snow fell in the Central Bear River Range in the evening and overnight. Yesterday, we found very nice shallow powder and dust-on-crust conditions on smooth slopes at upper elevations. Unfortunately, warm temperatures last week melted off most sunny slopes and forested areas, and there are many places with bare ground and only a skiff of new snow....
Remember to keep the speed down and watch carefully for shallowly buried rocks and other obstacles. Also, the Tony Grove Road is not maintained for wheeled vehicles in the winter. Expect patches of ice, deepening snow, and deteriorating driving conditions. |

RECENT ACTIVITY |
|
No recent avalanche activity has been observed in the Logan Area, and the shallow underlying snowpack at upper elevations is fairly dense and supportable... The few inches of powder from Monday and through the week are subject to a large temperature gradient with the cold air temperatures contrasting significantly with the warm October snow below. I noticed a tell-tail granular or sugary texture in the cold surface snow. This is faceting, indicating the potential development of a persistent weak layer which may well haunt us later on in the season |

One member of my party triggered an audible collapse or woomphing noise and shooting cracks in a freshly drifted area..... Northwest winds yesterday were certainly strong enough to build shallow wind drifts with the soft surface snow. Wind slabs formed in exposed terrain at the highest elevations and in and around terrain features like gullies, scoops, and cliff bands.... Even a small wind slab could spell trouble if you get caught and swept into trees or other terrain traps below. As usual, you should avoid wind deposits on steep slopes.... |

Its a good idea to practice with your rescue equipment in the early season.... Shallow, simple problems in snow, or even in urban leaf piles, are recommended. |

MOUNTAIN WEATHER |
|
The pattern will continue with fairly benign and cold conditions. Expect continued cloudy weather, but only a little snowfall as storms clip by from the north. A change in the weather pattern is likely around the middle of next week, with a milder and moist zonal flow in the works.... |
