this one is a multistem with 4 large trunks growing at slight angles, largest trunk about 12-16 inches in diameter, bark is uniform brownish gray, about 40-50 feet tall, buds seem much larger on other tree. any Oak experts here?
Both appear to be Red Oaks (there are many in that group) http://en.wikipedia.org/wiki/List_of_Quercus_species#Section_Lobatae HTH Chris
A close-up photo of the underside of a leaf would help a lot (and include a 15cm ruler for scale), as would location.
here's underside of this leaf, again location is amarillo tx. bud length seems to be 2.5 mm, bud length on other tree is 5-6 mm.
