Step 1 BENCHMARK LOCATION
| Directions to Benchmark: Come down trail from River Springs Community Centre 1950 Lodge in Port Coquitlam)
at the end of fence line (that is not just an opening for another trail) head to the oxbow - you will note that the trailer storage area is on the other side of hte channel and the benchmark is at the very end of this storage area. |
