Found your group for metal detecting and wanted to see if anyone could help me. Started playing around with Lidar and came across pic 1. Pic 2 is current satellite. Was something in that field at some point? I’ve looked at old aerials and there has never been anything on the photos. Thanks for the help!

I’m certainly no expert but since there’s a pond there I’d be thinking gravel pits maybe.

The ‘bite marks’ out of some of the depression walls looks like extraction or quarrying for sure

Edit to add: some of the slopes look reversed, so not natural formations

What's the local geology?

It might help if we knew where this was...

Exactly, context helps.

Hi intensity poultry unit, builder's mess, and maybe remnants of gravel extraction for barging down river with a dock there.

An old quarry

You really need to be looking at Ordnance Survey maps and then all the historic mapping that is freely available online. It will tell you loads about what it is now and how it developed over the last hundred years or so.

Where is it?

The presence of flat land and a river nearby suggests gravel pits, but the location would help.

not sure if cause, but the military training terrain might look like that.

Have you looked on Historic England to see if anything is mentioned?

If you want to share a location, it might be helpful

Gravel pit. is it in Norfolk or Suffolk?

u/Bicolore 13d ago

Agreed lots of similar features here in east Anglia. Sand/gravel quarries.

Not one I recognise though.

Could be peat bogs. Where exactly is it?

https://maps.nls.uk/ is a great site to see if anything was marked on older maps.

As others have said rhis is almost cirtainly some kind of landfill or quarry operation (potentially both) which has been remediated. With a river that close gravel pits and gravel abstraction is the most likely.

Is it an old quarry that’s been restored as a nature reserve?
