The upper crater rim of Vesuvius is capped by thick tephra deposits from the last eruption episode in 1944. The bedded tephra layers overlie a light-colored layer at the right, a lava flow that had been erupted earlier in the 1944 eruption. The steep wall beneath the 1944 lava flow cuts through pre-1944 lava flows.
