Perhaps a compliment for some, but certainly not for a tree. This common alder (Alnus glutinosa) has a cracking pair of ears at this co-domnant fork junction. A very tight angle, with a fair amount of included bark within. No real target beneath, though long-term will its retention be feasible without massive failure occurring? As it sits in a relatively sheltered area, perhaps; though it’s on the slope of a hill, and the wind may howl through at times. Forever a weak point, that’s for certain.
