A number of the "half-way points" such as Crater Lake and Mono Lake also have unique geologic features. Only a few have been identified.

A petroglyph, possibly 5,000 years old, near Santa Fe, New Mexico. Two circles of 19 triangles.
The artist's version (on the right) clarifies details and adds color and an additional circle of triangles.

The Oregon Vortex "House of Mystery" in Gold Hill on the small triangle between Crater Lake and Eght Dollar Mountain (not the caves).

Detail of the pattern of triangles formed by the vortexes open as tourist attractions.

This pattern of points was first identified by Dorothy Leon. DorothyLeon.com
