Moderate avalanche danger means there is still heightened avalanche conditions on specific terrain features and that human triggered avalanches are still possible. If you are going to step out - do so with caution.

• Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
• In areas where deep persistent slabs may exist, avoid shallow or variable depth snowpacks and unsupported terrain features.

On Tuesday several small wind slabs in the alpine were observed. Also one large avalanche stepping down to ground from a falling cornice occurred on Big Bend Peak.

Don't forget to post avalanche observations to the MIN.

Around 15cm of new snow this week sits on crusts on solar aspects, a melt freeze crust below tree line and old wind slab in exposed alpine

Below tree line is in a daily melt-freeze cycle. At tree line the mid-pack consists of multiple layers of sun crusts or facets. Depth hoar and basal facets at the base.
