tepetl (Mdz3v)
This element for hill or mountain (tepetl) has been carved from the compound sign for the place name, Tetzcoco. The stones (providing the "te" of tetl) have merged with the mountain, shifting the shape from the usual two-tone green bell shape, taking on the wavy purple and terracotta-colored lines of stones. The red line wraps around the yellow line at each end, following the curve of the bottom of the bell shape.

The peaks of this mountainprovide the hospitable place for a certain plant (tetzcotli) that apparently can flower in such an environment. The rocky outcroppings on the left and right slopes provide a phonetic clue ("te") that this glyph is meant to be read "tepetl." Of course, mountains also typically have rocks. Regarding the yellow and red horizontal stripes, please see the article on Interiors.
