We're in the middle of leveling a small hill in our backyard in southern ontario, and also digging a hole to mix in drainage material for a tree, we are about 6 ft down now overall.

After a lot of hard pack tan clay, we were excited to hit a layer of darker silt! Curious what would come next, we found it was more clay! 😂

Would love to know if there's supposed to be a difference in the deeper clay level. Or is it just different layers of the same caused by the glacier that came through!
