Observation: Turnagain
Location: Center Ridge / Tincan Trees / Sunburst
Groups toured out Center Ridge, the north part of Tincan trees, and Sunburst. Groups on Center Ridge and Tincan dug pits, and noted the presence of two layers of buried surface hoar. Stability tests showed variable results: propagation on the January 21 buried surface hoar and facets sitting on a crust in some pits, ECTX in others.
