The
Te Mari Craters area, Tongariro
Photo Craig Potton
| "If Red Crater conjures up images of a violent
and wildly expressionistic character, then the Maari Craters on
the northern slopes of Tongariro are perhaps the more classical
and composed counterparts. They convey a soft serenity that cloaks
their violent origins. Despite its almost perfect form, which suggest
a very youthful volcano, the lower crater probably began to erupt
about 14000 years ago. More recent activity in these parts all appear
to have come from the site of the upper crater. About 450 years
ago a vent in this region sent a massive 15-metre thick tongue of
lava flowing into the forests below Ketetahi. The present form of
the crater, however, dates from eruptions in 1868. It also erupted
in 1892 and again in 1896-97 showering ash to a depth of 50mm on
to the desert road. Throughout this century Te Maari has continued
to fume away from steam vents on the crater walls without any further
major eruptions." Excerpt
