Amethyst Peak

Amethyst Peak is a mountain that Avalon has taken a claim on and takes care of. It is well known for the purple flora all over the mountain, and mineralogists take interest in its natural permanganate salts within the rocks of the mountain which make the rock purple too.

Name
Amethyst Peak was falsely named after amethyst, a purple variety of quartz, because it was first thought the purple colouration of the rock under the mountain was due to amethyst. It was later discovered that it was actually due to permanganate salts that had formed due to the high amount of pyrolusite reacting with hydrogen peroxide. Some have suggested renaming the mountain after Avalon.

Geology
A lot of the mountain's rock is made of pyrolusite (which is essentially manganese dioxide). The manganese dioxide can react with hydrogen peroxide springs to form permanganate salts. It is unknown where the abundance of hydrogen peroxide originated, but it's theorised that water from a lake near the top seeped down slow enough that sunlight could convert the water into hydrogen peroxide. A variation of this theory involves a colder era forming ice exposed to sunlight for long periods of time without evaporating. A lot of hematite (ferric oxide) has also been found in the mountain, as well as some hollandite and manganite. Geologists have been unable to take many samples for research due to the Avalon guarding the mountain from anyone taking from the mountain. Avalon has been observed eating hematite (as the Aggron diet is mainly iron), but it's also theorised her purple colouration is caused by ingesting permanganate (which is known to have a sweet taste).

Flora and fauna
The mountain is covered in an abundance of purple flora. Known examples include but are not limited to: foxglove, grapes, lavender, lilac, passion fruit, orchids, plums, tulips, and violets. Avalon has been observed planting some of these types of plants, which explains the unnaturally high amount of purple flora. It is clear that Avalon's favourite colour is purple. While Avalon almost always plants purple plants, she's seen allowing all kinds of fauna to live on Amethyst Peak. However, she's still very weary of individuals from civilisation due to their tendency to take land and resources for themselves.
