evan though trees can add to the finnish i cant imagen a elk being able to rub a tree so evanly on every milameter of its rack. WASU did alot of studys on elk and it has to do with the velvet and how bloody it is when it comes off. the longer it stays on the whiter it is, the blood has dried up and shows more of the bone colar. comes off earlyer and the blood dries and stains it more. the tips turn white from them rubbing them on everything,trees ,shrubs the ground. lots of good info from WASU, u should see what they said about ageing wild game.
