Looks like Manzanita to me... Big burls under those suckers.... You could dig it up and make a pipe :DWhat kind of tree is that.
Well you know Manzanita is a close relative of Briar. They both grow large burls underground, and manzanita was used for pipes during WWI and WWII when briar was hard to come by.+1 lonestar, it is a manzanita. Very common here in Nevada County CA
