Apologies for the lower-quality photos. Growth habit is too large and expansive to be pure Q. john-tuckeri, but the leaf size (smaller but wide) and shape matches for a hybrid. Some of the leaves have the tooths of Q. john-tuckeri but others are a bit rounded and have slight lobing like Q. douglasii.

Nearby oaks include Q. berberidifolia, Q. lobata, Q. john-tuckeri, and Q. douglasii.
