Lava lava flows slowly (0.25 mph), with maximum speeds between 6–30 mph on steep slopes. An exceptional speed of 20–60 mph was recorded following the collapse of a lava lake at Mount Nyiragongo. The physical behavior of lava creates the physical forms of a lava flow or volcano. More fluid basaltic lava flows tend to form flat sheet-like bodies, whereas viscous rhyolite lava flows forms knobbly, blocky masses of rock. General features of volcanology can be used to classify volcanic edifices and provide information on the eruptions which formed the lava flow, even if the sequence of lavas have been buried
Nisga'a Memorial Lava Bed Provincial Park legend that accounts for the lava as well as geological causes. The park has waterfalls, pools, cinder cones, tree moulds, lava tubes, spatter cones, a lava-dammed lake, caves and other features created by lava flows. The park aims to protect moose, goats, marmots, bears and many other species of wildlife. The park covers 178.93 square kilometres in area. It is believed to be the site of Canada's most recent volcanic eruption and lava flow, a geological disaster that killed an estimated 2,000 people. The source of the eruption was the Tseax Cone. Large lava flows dammed the Nass River and
