Hi there,
Hueco Lodo was the original name of the place known by the locals before the name Mudgap was given. Beneath the old mining town flows the Rio Fangoso river which is believed the name comes from.
Gold was found above Mudgap Pass on Claver Mountain and several mines operated along Mine Ledge Road. The Solomon Mine was the most prosperous along with The Mina Fangosa and the Quaker Lode mines.
Around the 1930’s Mudgap mines were depleted and became deserted and Mudgap almost became a ghost town if it was not for tourists.
Not many people know about this place and some maintain it is a fictitious place but it certainly exists and it is found in Southern
New Mexico
Hope this helps
