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.

    As someone who was just scrolling new, what is this? I’m guessing you didn’t run ground penetrating radar in a public park, right 😂?

      Well, pretty close :)

      This is an electromagnetic scanner. It’s basically a magnetic coil that you pass electricity through, this generates a magnetic field in the earth directly beneath the scanner (about 1m around the device). If the earth is electrically conductive or resistive, it responds differently. Add a GPS and walk around with it… $40k soil mapper that you carry about to make a map and it doesn’t even touch the ground.

      I knew the foundation would be there because I went to The Nutcracker at the Royal Winnipeg Ballet this Christmas. Before the show, they had a big curtain over the stage with a picture of a giant mansion on it. During the introduction, the director gave a tiny history lesson, saying that this mansion formed the basis of the backdrop they used for the ballet, and that it was a real place, and that place is now Munson Park. A little googling later, and it turns out that this was the Richardson family mansion until the 1970s when it was bulldozed and donated to the city to create the park. The Richardson family also sponsors the ballet. I was just sort of closing the loop for my own interest :)

      I’ve previously reached out to the parks branch within the city about testing toys. They’ve given me tacit approval so long as I’m not disturbing anyone.

      I thought it would be locally interesting to people in Winnipeg ;)
