Graves

If You cannot visit those famous graves, they can visit You.
uploaded some point cloud files - you can use it to generate higher resolution stl files if your computer is capable of such task.
it would be good to cleanup this file a bit more before reconstruction.
i might upload reconstructions when i'll get my hands on machine with enough ram to crunch the task :)
edit : tried to reconstruct bit more and got some lessons learned:
1)closeup photos provide far better detail level than many overview photos in high resolution
2)64bit machine , ddr3 or ddr4 based, 16G quad channel or more - mandatory.

and http://www.cs.jhu.edu/~misha/Code/PoissonRecon/Version6.11/ can be some help on older systems, but the pvms alone bails out as it requires over 4G of ram for feature matching.
i did not attempt any slicing of such scans yet...
ofcourse those are over 2m high models but i bet someone with delta will
