You can easily trigger an avalanche on steep, wind-loaded slopes generally facing easterly directions near and above treeline. You can identify a wind-loaded slope by a wave-like snow surface appearance and the hard, hollow feeling you will experience when traveling on it and you will often see a cornice at the top of the slope. If you choose to travel in avalanche terrain avoid unsupported slopes with convex rollovers and avoid traveling above terrain traps such as cliffs or dense trees that will magnify the consequences of even a small avalanche. You can find safer travel options in wind-sheltered terrain, generally below treeline.
There is still a chance you can trigger a larger and destructive avalanche on deeply buried weak layers. To reduce your chances of triggering a potentially unsurvivable avalanche that breaks deep in the snowpack, stick to smooth, planar slopes that are consistently deep with no rocks or shallow points where you might be able to impact the weak layer.
