What physiographic province is Acadia National Park in?
Regional Geology Acadia National Park is a part of the New England Physiographic Province and shares its geologic history and some characteristic geologic formations with a region that extends well beyond park boundaries.
Why is Crater Lake so dangerous?
The Cleetwood trail is the only legal access to the lake,” McCabe said. Within the caldera, snow and rocks are highly unstable and can often cause rockslides and avalanches, according to the national park. “Crater lake is a volcano, and the soil is really crumbly, so if you’re on the soil its very hazardous.
Because there are so few nutrients in the lake as a whole, the moss colonies are rare homes to life such as tiny worms and crustaceans, which are fish food to only two breeds of fish that live in the lake–kokanee salmon and rainbow trout.
Does Crater Lake have fish?

What evidence is there that Crater Lake was once a volcano?
The lava flow forming Llao Rock filled an ancient glacial notch. Forming of the Crater. —Many geologists have concluded that the basin occupied by the lake resulted from the collapse and subsidence of the volcanic cone of Mount Mazama. This explanation was first proposed by J. S.
