Lemmy read the article for you. Yes.

The frost sits within the Tharsis area, the largest volcanic region on Mars, which hosts 12 large volcanoes. This includes Olympus Mons, which is not only the tallest volcano on Mars but is also the tallest peak in the solar system at the height of 18.6 miles (29.9 kilometers), making it around 2.5 times the height of Mount Everest, the tallest mountain on Earth.

Had a hunch so I googled the size of Phobos just now: 27 by 22 by 18 kilometers. Olympus Mons is larger than the bigger of Mars' two satelites.

Though it's probably more that I severely underestimated just how tiny Phobos and Deimos are. They feel bigger in Doom...
