In-Ko-Pah Gorge is a deep, narrow canyon or gorge in San Diego and Imperial Counties, California, and was originally known as Myer Canyon. Its head is at 32°40′17″N 116°06′05″W at an elevation of 2,240 feet (680 m). Myer Creek flows down the In-Ko-Pah Gorge from its source in the Jacumba Mountains at the head of the canyon to its mouth at an elevation of 846 feet (258 m), then eastward to its mouth where it settles into the sands of the Yuha Desert, east of Ocotillo. Boulder Creek enters the canyon at its confluence with Myer Creek, a little over a mile (1.6 km) below the source of Myer Creek, at an elevation of 1,775 feet (541 m).
