One handy way to keep track of the burrial chambers, is marking them on the map as you find them.
If you open your map, on the right are icons that you can select. Double clicking them on the map allows you to place them and write text under them.

Even if you dont need it right there and then, having some locations marked is quite nice for when you are in need of Surtling Cores (red cubes). So you can go to the closest one straight away.

You can either replace the icon with a different text (like Empty), or click the icon on your map with the left mouse click once to place a red cross through the icon.
That way you know what crypts are empty and what ones you havent visited yet.
