The windswept gravelly hills, formely known as extreme hills M or gravelly mountains, is a slightly altered and more desolate variant of the windswept hills. It is the second rarest biome in the Overworld, after the pale garden, covering only about 0.103% of the world terrain.
Description

True to its name, windswept gravelly hills contain large amounts of gravel that replace the top few layers of stone, grass block and dirt across its landscape. Due to the gravel replacing most of the grass, spruce trees and oak trees generate far less often, along with reduced amounts of dandelions, poppies, bushes and short grass, making this variant relatively barren. In Bedrock Edition, no trees generate here at all, and almost 100% of the biome is covered with gravel, with only a few 1-block wide strips of grass generating inside, allowing far less bushes to generate. Players should be careful when surfacing from underground in this biome, as the top layers of gravel can pose a suffocation hazard.
In other aspects, however, windswept gravelly hills resemble their regular counterpart: the terrain is still elevated and full of falling hazards, and generates hilly and shattered in some areas, often resulting in floating islands. Above Y=120±8, rainfall converts to snowfall, and snow begins to cover the ground. Water also begins to freeze into ice starting at that height.
Windswept gravelly hills share their foliage, grass and water color with windswept hills and windswept forests. Emerald ore generates here. On the biome surface, coal ore and iron ore is found frequently exposed to broad daylight. Underground, occasional infested stone with silverfish can be encountered. The deep dark cannot generate beneath windswept gravelly hills, despite being a highland biome.
Farm animals spawn their cold variants in this biome when possible, and llamas generate in herds around the biome.
This variant rarely generates in lower humidity values and colder temperature ranges than regular windswept hills and windswept forests. Because of this, windswept gravelly hills often appear next to plains, snowy plains, ice spikes, snowy taigas and uncommonly forests, sunflower plains and flower forests. As the biome is a variant of the windswept hills, additional requirements for locating the biome are high PV and high erosion values. On top of that, all windswept hills biomes are more likely to generate in higher continentalness.
