None of the ice is older than the year 1980, however, the volume of the new glacier is about the same as all the pre–1980 glaciers combined.

The ice is very thick, averaging of 328 feet (100 meters) and a maximum thickness of around 656 feet (200 meters); nearly as deep as Mount Rainier's Carbon Glacier.

Lake evaporation indicates a decrease in precipitation and cloudiness around Kilimanjaro.
"Less cloud coverage lets more sunlight filter through and hit the glaciers," Hastenrath said. "That increase in sunlight then provides more energy for evaporation of the glacier."

Others, including Hardy and Lonnie Thompson, who released the 2000 Ohio State University report, believe that colder air surrounding the glacier kept its walls frozen even as portions of the interior melted away.

The only mystery is why the lava dome didn't entirely melt the glacier. But it's quite normal for active volcanoes to have glaciers on them.

Uhhh. How about the fact that this glacier is growing in spite of the insistance from the GW people that all of the world's glaciers are melting?
Cooling rock on the outside of the dome insulated the glacier from the lava, and only about 10 percent of the glacier melted, said Carolyn Driedger, a USGS hydrologist. Instead, the dome, growing by a pickup truckload of lava every two seconds, split the glacier into two moraines – deposits of glacial rock and soil – pressing each against the crater walls. The pinching forced the glacier arms to double in depth and increase their speed
