I can see arctic dwarf birch Betula nana

Verify with 🔍︎ images.

Part of birch  genus Betula in alder / birch / hazel / hornbeam  family Betulaceae in bayberry / beech / birch / oak / walnut  order Fagales.

Native to the arctic tundra, and subarctic.  Definitely native to 🇺🇸 Alaska, 🇨🇦 northern Canada, and 🇬🇱 Greenland.  Some sources include Asia, which we interpret as 🇷🇺 Siberia, making it circumpolar.   🌎︎ Map (North America, Central America).    Thus, the shortest of all the birches.  By a lot!  Tree is never more than boot-top- or waist-high, and the leaves are tiny.

Uses by native peoples
(Ethnobotany database)

Betula hosts caterpillars of 413 species
of butterflies and moths, in some areas.
