Lost Crevasse is an Intermediate map for Bloons TD 6, introduced in version 50.0. It features an icy cavern where Bloons split into multiple groups as they progress, but they move slower than usual, and is surrounded by walls where bouncing projectiles can excel, but ice crystals prevent towers from being placed on some places.
Layout
Lost Crevasse's layout consists on a large land mass in the upper section surrounded by the Bloon's path and and a lower section divided in two parts separated by a column of crystals which block line of sight. The left side has more land area and the right side contains a lake where water towers can be placed. It has three paths that Bloons can take:
- Path 1 starts on the left entrance moving clockwise around the land until the right junction, here the Bloons keep moving around the top section until the left junction where they head towards the the left exit.
- Path 2 starts from the right entrance moving anti-clockwise around the upper section until the left junction, where they keep moving towards the left exit.
- Path 3 starts in the same way as the first one, but when the Bloons reach the right junction, they will continue towards the right exit.
All three paths are active at the same time and new spawned Bloons will alternate between them.

Development

This map was first revealed in revealed in the BTD6 Dev Diary #2[1], where Ninja Kiwi stated that the map took inspiration from Silas which was released in the same update. They also presented an early image of the map with slightly different layout compared to the final release. The main differences are the lack of the final bends towards the bottom of the map, the presence of ice crystals on the left and right sides and a slightly different placement for the water area, alongside simpler visuals in general, specially for the ice crystals in the middle.
This cool cavern was inspired by our new upcoming ice hero, you may have heard about around the banana stands.
A secluded place that the ice hero enjoys visiting during his time wandering, Lost Crevasse has an asymmetrical split path that shuffles Bloons into new groups as they move through the map. The walls at the edge of the path will eat projectiles but offer good opportunities for bouncing projectiles and zone-based damage. Large ice crystals separate potential tower placement, if only there were a new ability that could help overcome this hurdle...— BTD6 Dev Diary #2[1]
Trivia
- In the update preview video for version 50, this map was incorrectly named "Frozen Crevasse".
