Travel and Terrain Advice

Pay attention to time-lapsed wind slabs located at high elevations. This slab has a sluggish response to human stimuli, so it will not move without a large stimulus, but there is a possibility of inducing in topographic areas where snow cover is prone to instability, such as very steep, convex or unsupported shapes It is necessary to think and act. Also, at low altitudes, watch out for glide cracks and falling remaining snow blocks. Have a safe day
