A close-up view of the northeastern rim of the Halema‘uma‘u lava lake, at the summit of Kīlauea. This area of the lava lake has been degassing persistently for the past few months. Several large boulders, which fell from the crater walls, are visible near the perimeter of the northern lava lake crust (center). The top of the inactive northern vent cone is visible in the lower left. USGS photo by L. DeSmither on May 20, 2021.
