Hi Blake and Brianna,
This looks like a Skipper Caterpillar, more specifically, one of the Duskywings in the genus Erynnis. See BugGuide for some photos of the caterpillars. According to the Butterflies Through Binoculars The West by Jeffrey Glassberg, Oak is a the food plant for the caterpillars of many of the species of Duskywings.
