* Nitrogen ice: This is the most abundant ice on Pluto's surface, making up a significant portion of its plains and some mountains. It's responsible for the hazy atmosphere.

* Methane ice: Found in both solid and gas form, methane contributes to Pluto's reddish hue.

* Carbon monoxide ice: This ice is found in smaller amounts and is typically associated with nitrogen ice.

* Water ice: While water ice is present, it's not as abundant as the other ices. It's often mixed with other ices and contributes to the reddish hue of Pluto's surface.

In addition to these major ices, there are likely traces of other ices, such as ethane, ethane, and other complex hydrocarbons.

It's important to note that Pluto's surface isn't uniformly covered in ice. There are regions with different compositions and concentrations of ice, leading to variations in color and texture.

The presence of these ices provides valuable information about Pluto's history, formation, and atmospheric conditions.
