Yes, there have been pyroclastic flows associated with past eruptions of the Yellowstone Volcano. The most significant eruptions, such as the Lava Creek eruption about 640,000 years ago, produced extensive pyroclastic flows and ash deposits that spread over large areas. These clouds of hot gas, ash, and volcanic rock can be extremely hazardous, but the current state of Yellowstone is relatively stable, with no active pyroclastic activity.
No volcano has erupted in Yellowstone Park, at least not in recorded history.
The ash cloud of a volcano is called a volcanic plume or eruption cloud. It consists of ash, gases, and steam that are emitted during a volcanic eruption and can travel long distances depending on wind conditions.
A shield volcano typically does not produce pyroclastic clouds, as it primarily erupts low-viscosity basaltic lava that flows smoothly and spreads out in broad layers, creating a shield-like shape. Instead, its eruptions are characterized by effusive lava flows rather than explosive activity. However, if a shield volcano experiences a more explosive event, it could potentially generate a pyroclastic cloud, but this is not the norm for such volcanoes.
No, they are not the same. A pyroclastic flow is a fast-moving mixture of gas and volcanic material that can travel down the slopes of a volcano at high speeds, while an ash cloud consists of fine particles of rock, minerals, and volcanic glass that are ejected into the atmosphere during an eruption.
Yellowstone has produced both basaltic and rhyolitic lava flows. It is better known for its ecplosive eruptions, which produce large ash clouds and pyroclastic flows rather than lava flows.

a Pyroclastic Shield Volcano. Basically a shield volcano covered in pyroclastic debris from earlier eruptions.
A cinder cone volcano is made up of only pyroclastic material that results from a violent eruption. These eruptions typically eject a dense cloud of volcanic ash and other pyroclastic materials like rocks, and can have explosive and destructive outcomes.
Given that Yellowstone is in the middle of the United States, it is a mainland volcano.
No. The Yellowstone volcano is neither a mountain nor a composite volcano; it is a caldera.
A pyroclastic flow moves away from a volcano in all directions.
