I have seen elk scrapes. They are used just like deer scrapes. They look just like a deer scrape only 3 times the size. Last year my buddies and I stumbled upon one that still was wet with urine and smelled like pure RUT. It sure got us all fired up. I'm sure it does the same thingto the elk. LOL We were on a september bowhunt, but most rifle hunters may have not seen this because the rut is over and they are not using scrapes/rubs. I have no idea about Moose.
