Fentale, also known as Fantale, is the stratovolcano seen here from the Ethiopian Rift. Fentale lies at the N end of the main Ethiopian Rift and consists primarily of rhyolitic obsidian lava flows with minor tuffs. Welded pyroclastic flow deposits were emplaced when the 2.5 x 4.5 km summit caldera formed. The WNW-ESE-trending elliptical caldera has an orientation perpendicular to the Ethiopian Rift, and post-caldera vents occur along the same orientation.
