The dark-colored lava flow just to the right and below the center of this NASA Landsat image (with north to the top) originated from the Quimsachata (Kimsachata) scoria cone about 11,500 years ago. The smaller lava flow directly to the north that deflects the E-W-trending Vilcanota River was erupted from the Oroscocha lava dome about 6400 years ago. These are the northernmost young volcanic centers in Perú and lie at the foot of the Cordillera Oriental in an isolated area far east of the main volcanic front.
