Hello, and welcome to OSM! I wanted to drop a note. The correct tag for letters on a mountain is:

man_made=geoglyph

You can read more here:
https://wiki.openstreetmap.org/wiki/Tag:man_made%3Dgeoglyph

Additionally, it shouldn't be name=E, but instead, it should be inscription=E. The art is the letter E, which is an inscription, not the actual name.

You also mapped this as a line, you could make it an area.  Name needs to be removed.
