With apologies for the colour scheme (I'm so sorry if you're colour blind!). This is the lower layer of a two layer 1D inversion model, interpolated. Was playing with maximizing the contrast to try to find the foundation of the Richardson Mansion that existed on this property prior to it being bulldozed in the 70s and donated to the City of Winnipeg to become Munson Park. I'm pretty sure I captured it in the red square in the middle.
I assume the foundation is the squarish donut thing just down and right of center?
Probably. It could be a buried pool or some other similar squarish thingy ;)
