The Crystal Canyons of Chandrila were an enormous gallery of natural formations made out of rock and crystals, which formed a tight trench, with an abyss below it. The caverns were the site of the burial of the third Barsen'thor of the Jedi Order.
Some bridges and gaps were made to connect the two sides of the trench, and statues had also been made there.
In 14 ABY, during Jaden Korr's mission to Chandrila, he had to stop Tavion Axmis's Cultists from siphoning the Force from the tomb of the third Barsen'thor of the Jedi Order.
Korr had to make his way through the bridges and caves of the canyons, and was able to stop the Cultists and run to safety, but the tomb collapsed shortly thereafter.
