Valley of Ten Thousand Smokes The ash-filled valley covers a area. The ash can be up to deep. In places deep canyons have been cut by the River Lethe, allowing observers to see the ash flow strata. Since the ash has cooled, most of the fumaroles are now extinct and despite its name the valley is no longer filled with 'smoke' (i.e. steam). Vegetation still does not grow in the valley. The signs of volcanic activity are still visible on nearby hills. Katmai's most recent eruption was in 1927, but there have been non-eruptive events as recent as 2003. The Alaska Volcano Observatory still monitors
Places of interest in the Death Valley area when gas escaped from the cooling lava. Some of these have been expanded or even merged by sandblasting. Non-stop winds on this ridge are concentrated and compressed at the top of the hill and are very fast as a result. These strong winds pick-up dust and sand (mostly from the two closest alluvial fans), which literally sand-blast exposed surfaces. Winds strong enough for sandblasting come from the north and the south.
