What is the Oregon Lake Caldera or Volcanic neck?
It would have to be a caldera. A caldera is a depression in the ground, so it is logical that one would contain a lake (and some do). A volcanic neck is a pillar or mountain of rock that solidified inside a volcano, and so could not form a lake.
What is a circular depression formed by an explosion or a collapse at a volcanic vent?
The rare phenomenon you're talking about is called a calderas.Caldera is the term given to large depressions associated with volcanoes that form when volcanoes explode or collapse into the earth.
When is caldera form?
When a large explosive volcanic eruption destroys most of the volcano, the resulting large crater is called a caldera.
What forms after the top of a volcano collapses?
When a volcanic cone collapses it forms a caldera.
What type of volano is Mount St Helens a shield or composite?
Mount St. Helens is an active stratovolcano. Composite Cone volcano - APEX

If the top of a volcano is blown off what kind of lake can it form?
In cases where a volcanic mountain erupts, leaving behind part of its neck, to form a kind of depression or hollowed remnant called a Crater. When water gets into such cavity and becomes traped and stagnant it leads to a "Cratic Lake" mostly known as a "Caldera".

How is a crater lake different from a caldera?
A caldera is the depression atop a volcanic landform, either active or dormant. It can be very large and becomes less visible after a long period of erosion. A crater lake forms when the surface of the caldera is impermeable rock, and there is no way for precipitation to drain. On high mountains with glaciers, small lakes can form seasonally from meltwater.
How did volcanic mountain form?
by piles of lava
How does a caldera forms?
A caldera is a large depression in a volcano. Most calderas form in one of two ways: by collapse of the top of a composite volcano after the magma chamber is drained.

Mount St. Helens is an active stratovolcano. Composite Cone volcano - APEX
What is formed when a cavern roof collapses.?
Sinkholes form typically as limestone dissolves. A caldera is created by the collapse of volcanic vault ceilings.
Compare volcanic crater to a caldera?
A Crater is a bowl shaped depression in the Earth's surface. It could be made by an impacting meteor, an underground land collapse, or perhaps may be found at the top of a volcano [= collapse].A Caldera is of volcanic origin, (but without a noticeable volcanic cone), where there was an eruption after which the magma chamber collapsed and is now filled in. Yellowstone is one notable example, and the Taupo Lake another.
What is a cater in volcano?
A volcanic crater is the part from which the ejecta or magma are emitted. Commonly a conical depression is left due to the withdrawal of the magma chamber that created the eruption. Sometimes infilled with a crater lake. If the eruption was of the highly explosive variety, there may not be very much of a mountain form surrounding the crater. Examples would include L Taupo in New Zealand, and the Yellowstone caldera.
