Plancheite supposedly collected here in 1958 by Arthur Kingsbury (1906-68) is now considered "very doubtful" and probably from Arizona. This is one of a number of likely or definitely falsified Kingsbury localities.

Given the iron-rich nature of the mineral assemblage and its manganese-poor character, the strunzite should be validated from the more likely ferrostrunzite possibility.
