Grid corner elevations for Watershed 6

Watershed 6 is overlain by a 25 x 25 meter slope-corrected grid (see W6 map), delineated on the ground by red rebar stakes at each grid corner. The grid was surveyed in the 1960s. When measurements began, corner stakes were labeled with an X-Y coordinate system. Grid cells with more than 50 percent of their area lying outside the watershed boundary were not included and not staked. At the conclusion of the survey, the grid cells (or "plots") were numbered consecutively from the top left (west) of the watershed to the bottom. Each cell is now identified by a numbered aluminum tag at the base of the NW corner stake, and in some cases the old coordinates are also visible stamped into the aluminum tag.

The table below includes elevation data for each grid corner. Plot numbers designate the NW corner of a grid cell, so coordinates without a plot number are the corners of outer grid cells which do not define the NW corner of another cell. Slope and aspect apply to the entire grid cell. Till depth was measured with a sonar device in the late 1960s or early 1970s.
