VERY GOOD

Allthorn is a spiny shrub found in Arizona and New Mexico. Usually growing in dense thicket, the shrub is nearly leafless, is very hard and does not reach tree size very often. 

Arizona reports that very few were ever taken as bearing trees. Of those that were, all that have been recovered were found with open blaze and scribe marks legible. 

Keep the blaze small, probably only a "BT" blaze, and paint the wound to reduce weathering.
