Robert DeMoss believes there were several independent encounters between different groups over a large area. From my poor memory, there was one group of "loyal Indians" fording the Arkansas on the Dawson Road (near the present dam), another group crossing the Cimmarron/Red Fork at Keystone (under the lake just northwest of the north end of Dawson's Ridge), and a third at the Mann Ford on the Cimmarron. He believes Cooper split his forces which then encountered each of these groups. The groups were moving generally to the north side of the Arkansas. Some to old old Ft Arbuckle (the former site of the short lived post Dawson established which was northeast of the present dam) but such a large group would be spread over a large area with the old fort site (where they were digging caves) on the east and spread upstream around/along Walnut Creek for miles. Presumably they were moving close to their Keetoowah friends at the invitation of Capt James McDaniel, Reserve Company, 1st Cherokee Mtd Rifles (Drew's) who lived in the Skiatook/Sperry area. It is my opinion that they were not yet intending to go to Kansas but were moving very slowly away from Cooper and towards their Cherokee friends in Cooweescoowee District.

Dawson's Ridge seems a good candidate for the 'round end of a mountain' but there may be others as well. The site of THE Round Mountain is hard pin down, obviously! Tower Hill in western Tulsa County is a possibility and may be where the first 'encounter' of the day occurred with Opothleyahola's "scouts". Muriel Wright seemed to like a large hill north of Mannford and the Cimmarron (I believe DeMoss calls this hill "section 13" from it's legal description). Artifacts had been found there by locals and it seems to fit generally with distances after crossing the Cimmarron at the Mann Ford. DeMoss places THE Round Mountain further north -- north of the Keystone Expressway (Hwy 412/Cimmarron Turnpike) toward Westport. I'll have to dig out the precise info but this hill is adjacent to a northwesterly downward slope (that the highway follows now) into an inverted V with a creek at the northwest end (Round Mountain Creek?). DeMoss believes the Texans that crossed at Keystone met up with those that crossed at Mann Ford and fought in this inverted V. Having held off Cooper, the remainder of Opothleyahola's followers cross the Arkansas at present Osage and then move east to join the rest.

The above locations are consistent with the Cox Map which, if overlayed on a modern map, shows the flag marking the battle very close to DeMoss' Round Mountain and not too far from Muriel Wright's "section 13 hill".
