Written Report:
Similar to what Aaron was finding on Tumalo I found about 5 cm. of new snow that was mostly wind effected. However, at Todd Ridge which is mostly at and below treeline I saw no wind slab development. In fact I saw no evidence of any avalanche problems at all today. The new snow was overlaying a melt-freeze crust that was off and on breakable, and below that was over a meter of melt forms. It was a pleasant spring day with periods of sun, but also snow-showers. After such strong winds in town, I was surprised to find the winds mellower in the ski terrain at Todd. On the lake they were moderate, and then strong from the SW only at ridge-top. I saw moderate blowing snow at the ridge-top, and there had previously been variable scouring lower in the terrain. Weather and snow pack specifics are below. Notably a temperature profile at 6520 ft. was nearly isothermic for the upper meter of snow (temperature throughout the top meter of snow was uniformly 0 C).
