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.

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.

Look for weather products and tutorials at Avalanche Canada.

• 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.
