A middle Pleistocene paleosol sequence from Dawson Range, central Yukon Territory

Four paleosols were intersected in a core drilled into the colluvial fill o f a largely buried meltwater channel that was last active during the younge st of the pre-Reid glaciation (0.99-0.78 Ma) in the Dawson Range, Yukon Ter ritory. The paleosols are classified as Podzols. The sedimentary sequence a nd paleosols indicate that at least two middle Pleistocene glacial and inte rglacial periods are represented in the core. The mean annual temperature e xceeded 0 degrees C for thousands of years in the upland environment of the Dawson Range at 61 degrees N during these interglacial periods.
