It is unclear whether Pendan is an actual volcano, a misidentified mountain or valley which may or may not be of volcanic origin, or a copyright trap fabricated by the Smithsonian Institution.
The authenticity of Pendan as a volcano is doubtful; it could be an actual geological formation, misinterpreted as a mountain or valley with possible volcanic connections, or potentially a deliberately created geographical feature designed to mislead by the Smithsonian Institution.
