ELLIOT CREEK. Elliot Creek rises two miles northeast of Marietta in northwestern Cass County (at 33°13' N, 94°31' W) and runs west for three miles to its mouth on Mill Creek (at 33°13' N, 94°34' W). The creek traverses an area of gently undulating to low-rolling land surfaced by loamy soils that support native vegetation including water-tolerant hardwoods, conifers, and grasses. The area around the creek is flood-prone. The creek was named for James Elliott, the original grantee of land near its upper reaches.
