<p><span>In this informal paper the processes of snow‐wastage at high altitudes were discussed and a number of slides illustrating </span><span>suncups</span><span> and </span><span>sunpits</span><span> in different stages of development were shown. It was stressed that these features are peculiar to the region above the timber‐line, which biologists term the Alpine, or Arctic‐Alpine, Zone. That regions is, as a matter of fact, primarily and fundamentally a physiographic zone distinct from all other physiographic zones at lower levels by reason of an unusual combination of climatic, hydrologic, and geologic factors.</span></p>
