"Little" biome areas tend to be devoid of certain resources, and is better to find larger biomes...

To "know" whether or not, the unexplored swamps hold crypts, means you will actually have to go there, and whether you build shelter there or not depends on if there are crypts there, BUT, the one thing you don't have to know ahead of time is that, ANYTIME you travel away from your main base, especially if its to a different island, you absolutely want to bring supplies for a portal, and should be amongst the first things you set up when you reach land (BEFORE you explore to see if the new swamps hold crypts), that way if you die while exploring you have a way to get back to your stuff.
