Used recommended coords from cachemando2, but still took a while due to bouncing GPS signal. Benchmark is in fine shape.

Found as described. While son & friend was riding at skate park.

I was able to sneak a peak just before a train came by.

Now I am embarrassed... I used to have a clue very near here for one of my multi, and I never noticed the B/M coming and going doing maintenance on my stop... So thanks for bringing me back to the park.

The rails were raised to make Garden of the Gods Road an underpass about 1980. In the process, the bridge for this marker was replaced with a new bridge over the creek. BM is most likely to be destroyed.
