Nelia, Laura, and Aaron skidooed out to Kachina where Aaron and Nial had recently completed a DistoX / transit survey with a DGPS unit to test whether it would be reliable underground. The unit behaved somewhat erratically, sometimes jumping from zero to nine satellites. At least twice during the survey the power cable for the receiver came out.
