SAN CAJA HILL. San Caja Hill, also known as Lomo San Caja, with an elevation of 482 feet, is one of a group of hills in southern McMullen County (at 28°16' N, 98°23' W). The site was visited in 1689 by Father Damián Massanet, who called the elevations Sierra Sacatsol. The name San Caja is supposed originally to have been Sin Caja, meaning "without coffin." The change to San Caja was probably made by English-speaking persons who assumed that the site was named for a saint. The word caja, which also means box or chest, is said by some to refer to hidden treasure. According to legend, Mexican bandits at one time had headquarters in a cave in the west side of the mountain where they hid the loot from raids on wagontrains traveling between San Antonio and Laredo. The surrounding low rolling to flat terrain is surfaced by sandy and clay loam that supports scrub brush, cacti, and grasses.
