Worst Weather ascent of the year. Shalee, Tony, and I got a campsite down by heart lake, and the hiking was a little snowy to start but nice and dry towards the lake. Since it was clear at least the first 1000 feet, Tony and I decided to go for it. Towards the top was brutal and it was high winds coupled with 1-2 feet drifting snow with almost no visibility.

Lookout in great shape, sure would have been nice to warm up in it.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in January 1997.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
