The group started out by packing the snow down to form a solid base for their snow cave. The snow was a out 3 feet deep; not quite deep enough just to tunnel under the snow. So a bit more work was required.
Making a large mound of snow to dig into.
Fully tunneled in, the process of expanding the inside begins.
After about 2 hours from when we started, we have a comfy, roomy snow cave.
The final product from outside.
