Aye: looking at who might move in afterwards as a springboard for some runs.It is still a powerful magic site?
I understand the Shasta Shamans *appear* to have gone the toxic avenger route. Add in Ryumyo trying to control the Ring of Fire ( and parties interested in preventing that), potent magical groups like IOND and the Black Lodge, Japan Corps, Wuxing, Aztechnology, SK, the possibility the NAN would want it declared a shamanic holy site, the Cal Free Guv'mint: it seems without a GD or IEs openly active in the area there are a lot of potential shadows for the Mt Shasta macguffin.
