Air photo from the Geologic Survey of Ethiopia shows two lobes for this caldera. The main road from Addis Ababa to Djibouti passes along the join of the two collapses. The floor of the larger lobe on the west is filled mostly with older, light-huedlava, but two dark flows from fissures on the rim flow across part of the floor. The smaller eastern collapse crater is completely filled by dark lava flows. Local legends suggest this lava erupted in about 1820 AD.
The color photo was taken from the road and shows the floor of the smaller caldera. The older name of the caldera, Gariboldi, supposedly comes from the engineer who built this road during the Italian occupationof Ethiopia in the early 1940s. The new name, Kone, is a local tribal word. Photo and captions by Chuck Wood.
