Quoting from Reynolds, et al., 2009: Two main major units of the Bishop Tuff deposit are visible here. The lower 1512 feet of the section consists of the poorly-sorted airfall tuff that was deposited downwind from the eruption of the Long Valley caldera. The upper 15-2018 feet of the section consists of the basal portion of the pyroclastic flow that comprises much of the Volcanic Tableland to the west. At this location, it is remarkably well-sorted for a pyroclastic flow. The dark layers" just below the contact between the two units are manganese oxide stains resulting from produced by groundwater circulation. Statistically, the four sample locations/units are indistinguishable. This supports the theory that the Bishop Tuff was emplaced in a single event over a limited span of time.
