During the related quest, they can be harvested for their bark. There are five Canticle trees found within the glade, which appear as trees covered with white and pink blossoms. (Note: this is one of the areas that was targeted for extra plants in Skyrim Special Edition, so the counts are much higher in that version of the game and are listed separately from the counts for the original game.) Ingredient Hanging moss is entirely within the initial cavern, while most other plants are found within the glade itself. The following harvestable plants can be found in the area. The items can easily fall off, so it's worth scouring the ground nearby and downhill from them if an item is missing. There are many piles of rocks, all found against the outer walls of the main glade, which have items of treasure on top. During the related quest, there is a wooden gate that will close behind you as you enter the main glade, to prevent you leaving prematurely. If you have not yet started Unseen Visions, you'll be ambushed by three spriggan earth mothers in the first area of the cave, regardless of your level. Another path on the left follows the wall, leads you across a fallen tree, and then into another short tunnel opening up to the main glade.
The entrance descends into an overgrown passage that leads to a dead end.
Everything in and around the campsite is marked as owned and, as such, taking anything is considered stealing, although you can skin the dead ice wolf without committing a crime. Beside the campfire are an ice wolf pelt, a snow bear pelt, a dead ice wolf, an unowned bed roll, and a novice-locked chest. One contains a salt pile and the other a venison chop. A few paces to the northeast of the entrance, behind a large rock, is an old campsite complete with an extinguished campfire, with two pots hanging over it. The entrance is high in the mountains, above the snowline east of Falkreath, south of Pinewatch.
