Doing this after the fact, so may be incomplete (but written jointly by Steve, Chris, and Tony):

Weather was fantastic: warm, partly cloudy, not too windy.

After every break, a load was brought back to the U-Haul (parked at RMBL). The 2 track to kettle ponds was muddy but passable with the GSA trucks.

Tues: Onsite: Chris, Tony, Will, Josh, Justin, Terry, Brigitte

  • Performed safety brief (Need to update the JHA form to flow with briefing)
  • remove PI sensors and started removing all sensors that were reachable from ground level.
  • removed all sensors from UE and UW
  • removed all sonics from Center tower
  • Lowered UE  (in one piece)
  • removed all power boxes and power cables (NOTE: BX Cable survived just fine under the snowpack)

Wed: Onsite: Chris, Tony, Will, Josh, Justin. Terry and Brigitte left at 1, replaced by Steve

  • Lowered UW (in one piece used pulley system attached to anchor)
    Would it be possible to use a GriGri or elevated safety to lower towers
  • removed all TRHs and DSMs from Center tower
  • removed all equipment from D
  • removed anchors as towers were lowered

Afternoon break, then:

  • Took soil core
  • Lowered d tower (in one piece).  Only had one person on a side guy and tower slipped that way during lowering.  Should have had someone on other side guy!
  • Removed soil sensors
  • Dismantled c tower from 70' to 20'
  • Left site about 1845 – another long day!
