Lidar. Opinion: Revolutionary War British Encampment?

[scrapmagnet]

I stumbled upon this after looking at a British encampment map from the revolutionary war and getting curious. The surrounding area is heavily developed with the majority of the encampment area now covered by housing. This area, after looking at historical aerial photos, seems to be undisturbed and wooded.
These berms stand out like a sore thumb. I did read that the British did fire artillery on the colonials from this area. Is anyone familiar with the general design of British (shorter term) artillery fortifications? The only place that I could come up with to compare was the defenses at Valley Forge. Granted, Valley Forge was obviously not British, probably different ground/soil conditions and longer term. The Lidar does compare pretty closely as far as the thickness and height of berms after 250 years of erosion.

Note: The ford is outside of the image and the ridge across the top was raised to accommodate added transportation infrastructure.

As far as who did what from where goes... For me... this would only be speculative without actually seeing the lay of the land in person... and even then...without trace evidence from research or hands on digging area looking for clues it would still only be guesses.

As far as direction of action... well... this has to be deduced via hands on... not from this Lidar image.
The layout does not necessarily mean "direction" of any one advance.

Thanks for your thoughts. Here is a section of the British map. I have placed a red X at the approximate location of the berms. Being it was hand drawn, scale and distances obviously won't be accurate, but it does seem to match up pretty well to a current map. The surrounding area is almost featureless and to my eyes, the berms do seem to have some thought behind them. Outer line at the top and secondary berms behind them. Although now wooded, it is my understanding that the area was cleared in the 1700's.

That said, yes, an on the ground view is the only way to positively confirm. Permission may unfortunately be difficult, but I figured that I would get some opinions before trying to get access permission and possibly traveling.
