Quick report

Nothing noteworthy in addition to above. In a 123cm snowpack, CTN. I performed a Deep Tap test; these tests are done for testing instabilities below the top 100cm. I wanted to test the 20241126 MF/ZR crust that was 69cm down so I in effect applied a Deep Tap test by removing snow down to 84cm and tapping away. I got a DTM Score 12 that was a surface planar result.
