What is the recommended angle for placing a vertical picket in weak snow?

The recommended angle for placing a vertical picket in weak snow is 15 to 45 degrees. This angle provides a balance between effective anchoring and stability in the snow. When a picket is placed at this angle, it reduces the likelihood of the picket becoming dislodged due to the force exerted on it, which is particularly important in weak snow conditions where structural integrity may not be reliable.

Placing the picket at a steeper angle, such as 45 to 60 degrees or 60 to 90 degrees, can increase the risk of failure because the picket may not engage the snow effectively, leading to a higher chance of pulling out. On the other hand, an angle of 0 to 15 degrees does not provide sufficient grip and support either, as it may not penetrate the snow deeply enough to resist the upward pull when load is applied.

Overall, the 15 to 45 degree angle strikes the optimal balance needed for securing the picket in weak snow conditions, ensuring adequate resistance against potential forces exerted during rescue scenarios.
