4. Results and Interpretation

4.1 Geochronology and Thermochronology

We sampled bedrock along the west and east sides of the Totschunda fault on several mapped and previously unmapped small hypabyssal plugs and a small Cretaceous gabbro body (Figures 3, 4). Sample 19SOLO06 was collected from a lateral moraine just downstream from a prominent outcrop of hypabyssal intrusive where this sample clearly originated based on lithology and travel trajectory (Figures 3, 4). U-Pb LA-ICP-MS zircon dating was performed on four of the six bedrock samples from the Lime Creek drainage, and seven of the eight detrital cobbles (Figures 3, 4, 5, 6). We report 14 AFT analyses: six from bedrock samples and 8 from cobbles from the White River ‘Tillites’ (Figures 3, 4, 5, 6). (U-Th)/He analyses were undertaken on apatite separates from 6 bedrock samples (6 grains per sample) and one zircon separate from a bedrock sample (19SOLO02; 3 grains) from the Lime Creek area.
