Walter Mruk (1883–1942) was an American painter who was a member of Los Cinco Pintores a group of artists who worked in Santa Fe, New Mexico in the early twentieth century.
[3] In 1924–1925, Mruk and fellow painter, Will Shuster travelled to Carlsbad Caverns on a painting adventure before the cave system was established as a national park.
He filled the cavern with mythical grotesques in an effort to interpret his reaction upon entering the dim lit interior.
The work is accepted as a distinct achievement, although decidedly unusual, and difficult of treatment.
[4]One of Mruk's paintings from this series is housed in Denver Art Museum.
