Desert Boulder Fields, like perhaps every SkeletonKey Games PDF, includes an overview of the different tiles before going to the full page images. These preview and instruction details only take up two pages and the rest of the file, another twenty pages, are tiles of the sands and boulders. The thing I like about these tiles is that there are a few that allow for some quick use that isn't necessarily just a desert tile.
For example, DBF11-DBF14 could all be linked to showcase a desert encampment that the party can stumble upon. Because of the natureo f the tiles, if you want the party to run across a larger group, you can print more tiles. DBF16 and 17 can be used to represent a stone trench that the party can seek shelter from. It's a nice variety of material.
Even better news, the product is on sale; $4.00 instead of $7.99. A cheesey quote might end this by saying, you can't hide those savings in the desert.
