In addition to the advice you've already gotten, the reason your 3D
model is so "wonky" is that you don't have elevation data outside
the region you plotted, so these all have elevation zero. Since the
region is around 8500' elevation, that creates the vast wall effect
you're seeing. <br>
More fundamentally, however, is that you are taking an unnecessarily
difficult path to creating this model. You can download a 1/9
arc-second DEM from the <a
href="https://apps.nationalmap.gov/downloader/">National Map</a>
which gives you a highly accurate elevation model for the entire
region, eliminating the problem you're having. <br>
