If it's flinty, don't use Schwalbe. I ride almost entirely flint around here in Devon and the only worthy tyres are Continental with ProTection or Maxxis with EXO casings.
For Tour Divide I used (and I also use around here) on my 29er Continental X-Kings, fast rolling, mostly grippy enough unless the mud is super squelchy. I think they do 26" too... don't forget ProTection sidewalls and tubeless...
