Pretty odd to run into two dual-summits (after Eureka, which I posted a couple weeks ago) in such quick succession.
White Mountain, near Antero:

Mount White is a dual-summit peak. The eastern summit is covered with white rock, possibly the same chalky rock as is common in the area; there is a cairn but it's well below the big boulders right on the summit. The western summit, in stark contrast, is covered with black/reddish rocks; a large cairn raises the "elevation" of this summit a couple of feet. The image on the peak page shows these summits pretty clearly.
They are visible on the topo map as well, as a contour line conveniently intersects the saddle. That would give 40 feet of interpolated prominence to the lower peak. It takes well under 5 minutes to walk between the two points, so perhaps it doesn't matter which is higher. The USGS has neither one listed as "Mount White", but rather pinpoints the more visible false summit (13371) off to the east (this is from the USGS points list; in the quad map the whole mountain is labeled). So perhaps this is just unranked peak 13667.
LoJ has the western summit labeled as highest. It's really hard to tell, but I suspect the eastern is higher.
1) The below pictures are not particularly clear, due to very different backgrounds. The "horizon" as a reference point is not visible to the west.

2) My barometer showed 0.28 mbar lower on the eastern peak than the eastern (622.88 versus 623.16). This corresponds to about an 11 foot difference, but is unreliable since ambient pressure could have changed.
3) My phone claimed looking at the western summit was 2 degrees down. From the western summit looking at the eastern it claimed 1 degree up. These numbers are even less reliable.

4) 13ers.com lists the eastern as the true summit. Summitpost does also. I have no idea how they arrived their conclusion. The eastern summit does *look* higher since it has the Arkansas valley in the background, instead of a bunch of 13000-foot ridges.
5) I didn't find a summit register on either point, though I didn't look hard.
