Trail Ruins

Trail ruins are buried structures which work as archeology points where both suspicious sand and suspicious gravel generate. The trail ruins may be found in a few temperate, cold and snow-covered biomes and come in different sizes varying from ruined villages to single ruined huts "from a lost culture."

Structure
A trail ruin may be found on land or underwater, typically nearby a river, an aquifer or an oceans. A large portion of the structure is found buried under the ground sometimes generating in the snow-covered snowy taiga biome or in taigas and old growth pine and spruce taigas cold biomes and in old growth birch forest and jungle temperate biomes. A trail ruin is the only natural source of mud bricks materials.
