I've seen where bucks will vist scrape locations - in the middle of the summer - but they usually don't scrape the ground - sometimes they just lick the branches or urinate.

When Scrapes like you just found pop up overnite this early - its usually a bachelor group that is showing off for each other more than anything else - same with concentrated early rubs. You find these alot early on field edges and in stage areas near food.

I don't think age has a lot to do with early scrapes (lone big rubs are another story though in my book)
