A motorist traveling through Tijeras Canyon catches his first glimpse of Albuquerque at the eastern edge of the East Gateway community. The three dominant features of the community--the Tijeras Arroyo, Central Avenue and Interstate 40 --converge through the canyon, then separate, dividing the community into three distinct areas. The Central American isthmus hosts a highly variable Moho structure due to the diverse origin and composition of the crustal basement and the influence of large-scale neotectonic processes.

The most recent period of arroyo formation in the southwest, which occurred from about 1865 to 1915, was not unique. Previous cycles of arroyo cutting (erosion) have occurred at about 2000 years Before Present (B.P.) and 700 years B.P. (Emmett, 1974). These cycles of arroyo cutting were both followed by slower periods of filling (alluviation).

Galisteo Creek borders the southern flank of the Cerrillos Hills and flows east to west, to the Rio Grande. San Marcos Arroyo cuts through the southeastern part of the Cerrillos Hills and joins Galisteo Creek at the village of Cerrillos. Both streams flow intermittently, though Galisteo Creek usually has at least a trickle of water.
