Description
Summary:An expedition to the subarctic mountain of Campsite Peak, Yukon Territory, within the Kluane National Park and Reserve (KNPR), was conducted during the summer of 2019 to investigate two undocumented periglacial forms identified in satellite imagery. The overall goal of this MSc research is to present and measure these two features spatially, morphologically, and sedimentologically, placing them within the periglacial literature and hypothesizing plausible formative processes. The first study documents a feature similar to stone-banked solifluction terraces, termed blockslope terraces (BSTs) within this research, and are found in large numbers on low- to mid-slopes of Campsite Peak above the treeline, mantling a blocky open matrix of ignimbrite cobble-to-boulder material. BSTs differ from expected solifluction characteristics by showing apparent periodicity, large sample sizes, oblique orientations relative to their slope, and material too coarse to support the formation of ice needed for active solifluction. ...
