Honestly kind of hard to do. If it is done properly there should be absolutely nothing to see.

Except for some stepping sticks or shoulder guides at the set, the trap can be set at ground level or recessed and bedded below grade. I do both.

Pulled anchors create fresh dirt.
Fresh dirt creates a lot of digging.

In the past I got a bunch of digging on pulled sets.
Every single dig was right on top of the anchor spot.
Your coyotes might act differently.

I'd put fresh dirt down ur pipe next time then
