In-Ko-Pah Gorge, Canyon in Imperial County, United States.

In-Ko-Pah Gorge is a deep, narrow canyon in San Diego and Imperial Counties, California, originally known as Myer Canyon. Its head lies at 2,240 feet in the Jacumba Mountains, where Myer Creek begins; Boulder Creek joins it just over a mile downstream at 1,775 feet. Myer Creek leaves the gorge at 846 feet and drains east into the sands of the Yuha Desert beyond Ocotillo.

Originally known as Myer Canyon, the gorge served as a natural passage for Native American tribes traveling through the region. It later became part of the Interstate 8 highway corridor, transforming it into a modern transportation route.

This natural corridor in the California desert connects different ecosystems, from the Jacumba Mountains to the Yuha Desert, influencing local wildlife patterns.

The interstate highway passes through the gorge and drivers should monitor weather conditions as rockslides can occur during storms. Travel is easiest during dry periods when visibility is good and road conditions are most stable.

Interstate 8 crosses the gorge on two separate alignments: eastbound traffic runs through In-Ko-Pah Gorge, while westbound traffic uses Devils Canyon instead. In 2023, Hurricane Hilary brought a massive rockslide that closed the highway here.
