We re-visited Calistoga again, this time we got the correct cemetery. This site is open to the public from dusk to dawn, as many cemeteries are; however, it's right next to a very busy street. The best time to go would be as the gate opens at sunrise (please do not trespass at night, as it's illegal). It's a very old site where many graves are falling apart, though there are some newer family plots as well. It's a very steep hill, an odd place for a cemetery, but fairly large as far as historic ones go. In terms of history, this site is the resting place of a couple of the original Donner-Reed party pioneers.
Thanks to the non-stop vehicle traffic, it's very difficult to obtain EVPs here. That being said, there were a lot of voices captured, but most were just drowned out by cars to list. But from what was captured, it sounds like there's actually several spirits here in a residual haunting. They are communicating with each other, mostly unaware of our present time. It would be a great place to go at night if you can arrange it with the city. There were more female presences than male, and to note: both Donner party survivors buried here were female.
With limited audio capability, we turned to using EMF and thermal to detect anomalies, but no activity showed up on our equipment.
