The Caxcan, an ethnic group in southernmost Zacatecas, northern Jalisco, and part of Aguascalientes, south to Lake Chapala and to the Río Grande de Santiago.
When Spain invaded, their leader Tzitlali, moved them away to a small valley surrounded by high mountains, a place they named "Cocolan.
They later centered themselves in Ixtlan del Rio, Nayarit, and created beautiful and elaborate round temple to their wind god, and other municipal buildings.
In 1310 a group of Coca tribe were led by "Big Eyes" to a safer place in a valley with steep mountains by the largest lake in central highlands.
Chief Big Eyes had probably traveled past the west end of Lake Chapala before, or at least heard of it from the generations of Shaft Tomb culture in that area.
Stories are told of how the Spanish also took some of the Coca tribe and much of the rock from the mountainside above them down to the west end of the lake, now known as Jocotepec, to build a chapel there also.
