Where is Crater Lake located at?

Are there fish in Crater Lake?
Fish are not native to the lake. They were introduced in the lake from 1888-1941. Six species were originally stocked, but only two have survived to today: Rainbow Trout and Kokanee Salmon.
What animals live in Crater Lake?
With many different mammals, amphibians, fish and birds, Crater Lake is home to plenty of wildlife. Deer, squirrels and birds are most common, but visitors exploring the forests and trails might encounter elk and bobcats.
Is San Andreas Fault a plate boundary?
The San Andreas Fault is part of a transform plate boundary that disrupts the topography of an ancient subduction zone. The transform plate boundary is a broad zone forming as the Pacific Plate slides northwestward past the North American Plate. It includes many lesser faults in addition to the San Andreas Fault.
Can you go to the island in Crater Lake?
The best way to see Crater Lake is by boat! For visitors seeking to explore Wizard Island, we offer either a boat cruise or a quick shuttle ride straight to the island. There is a 2.2-mile round-trip trail (down to the boat dock and back) that drops approximately 700 ft.
What rock is Crater Lake made of?
Most of the rock in the vicinity of Crater Lake is porphyritic andesite, a volcanic rock intermediate between the acidic rocks containing much silica and alumina, and the basic rocks containing the ferro- magnesian minerals. Andesite is typically light gray to dark gray in color, sometimes almost black.
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.
How dangerous is Crater Lake?
Hiking and climbing inside the caldera are strictly prohibited. The only exception is the Cleetwood Cove Trail, the only safe and legal access to the lake shore. Serious injuries and deaths have occurred from falls inside the caldera. The walls consist of steep, unstable rocks and soils.
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.
Is Wizard Island an active volcano?
Wizard Island, a post- caldera cone of Crater Lake caldera, erupted some 300 years after formation of the caldera about 6850 years ago.
Do animals live on Wizard Island?
Mammals, birds, and insects makeup the largest portion of animals living throughout the park. Native and some invasive fish species occupy many of the streams. A few species of reptiles thrive on Wizard Island and in dry habitats.
Is Crater Lake still active volcano?
The volcano’s compound edifice has been active relatively continuously since 420,000 years ago, and it is built mostly of andesite to dacite until it began erupting rhyodacite about 30,000 years ago, ramping up to the caldera-forming eruption.
