Step 1 BENCHMARK LOCATION
| Directions to Benchmark: walked in from corner of 17th St and Wolfe St down the stairs - headed south on path and went to area that many people go up and down to stream. Tires in stream and concrete cylinder blocks in stream. Wide open are (might consider planting here) |
