Tucumcari Mountain follows Bulldog Mesa. The origin of the word "Tucumcari" is difficult to trace. At one time, the area was in Comanche territory and these Indians were reported to have used the peak for smoke signals across the valley to the plains. Since the Comanche word for a lookout spot is "tukamukari," and since the mountain was an excellent vantage point for raiding Comanche war parties, this meaning of the word makes sense. More romantic, however, is the legend that surrounds this name. The folktale revolves around two lovers -- Tocom and his Apache girlfriend, Kari. According to the story, Tocom was murdered by his rival, Tonapon. In her grief, Kari killed Tonapon and then committed suicide. When Kari's father, Wautonomah heard the news, he stabbed himself, crying out "Tocom! Kari!" as he drew his last breath
The Driftwood song uses the Apache names mentioned above. As a kid, I also heard another meaning of Tucumcari, but it was a bit lewd.
