Discussion: Pits from past mining activity

This would make great orienteering terrain.

Interesting coincidence, yesterday I ran a course on a local country park in Scotland that it’s previous life was a coal bing.

Wheal Florence (now sadly buried under a spoil heap itself) was the best example of that sort of terrain I've seen.

jcampbell the topographic centerpiece of the area you and I have been discussing is the remnants of a 140 year old phosphate mine pit.
The remnants of phosphate mining are strewn all over Florida but none have I seen go so deep or stay so dry as this one.

I can confirm that former coal mines make for extremely interesting orienteering terrain.

Come to OZ or NZ sometime if you want mining terrain, we've been using it for eons.

A few years ago I went to a multi-hour event in West Virginia on reclaimed coal mining land that is now a Scout camp. Could have used a better map.

From what I've seen in the US, Finger Lakes SP near Columbia, MO is of this kind, IMO of high value for orienteering

Simmo has been around longer than they've been mining in this country.

Mining (gold and tin) had stopped 100 years before I got here. I was just in time for the nickel boom, then iron ore and bauxite started and finally gold again. Now it's lithium.

19th century gold and tin are the best mining areas for O. Nowadays the rehab makes the terrain even more boringly featureless than it was before the mining.

There are a couple of mapped areas in Sacramento along the American River which are covered with rockpiles, tailings from 19th century gold mining. There's an event this weekend at Rossmore Bar. The other map is Mississippi Bar nearby.
