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." Like ocean monuments, trail ruins have no chests; moreover, their loot is found in the aforementioned suspicious blocks.

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. The structure is composed of a central tower made of terracotta and glazed terracotta, the tip of which is the only part of the structure that does not generate underground, and a road made of cobblestone, stone, stone bricks, and its variants. Along the road can spawn small buildings and other decor made of mud bricks and terracotta. The entire structure is buried by sand, gravel, coarse dirt, and dirt, as well as some suspicious sand and suspicious gravel.
