The Colonnade meets Treeumphant Passage at a narrow angle. In one direction Treeumphant Passage ends just next to its entrance at a boulder slope. Ascending this leads to a fork; the left branch is blind and the right branch ends shortly afterwards in a choked chamber. In the other direction, Treeumphant Passage continues over large boulders going slightly up hill. There is a walking passage off to the left [C2000-204-24 A], as well as a high up crawl to the right [C2000-204-25 C] and then a tight high passage to the left [C2000-204-26 C]. The passage then increases in height approaching a sharp turn to the right. Here a walking size passage [C2000-204-28 A] continues straight on, and there may be an aven in the ceiling [C2000-204-27 X]. The main passage passes possibly diggable holes at floor level [C2000-204-29 Dig], and continues into Great Oak Chamber.
Treeumphant Passage disappears into an approx 5m drop [C2000-204-32 B] in Great Oak Chamber and there is an aven above [C2000-204-33 X]. There may be passage continuing straight across the chamber [C2000-204-31 B], as well as a passage to the right [C2000-204-30 C]. Just before the drop there is a bouldery slope up to another smaller walking size passage. There is an oxbow to the left, with a possible passage leading off it [C2000-204-34 B], as well as an aven [C2000-204-35 X]. There are a couple of possible digs to the left slightly further on [C2000-204-36 C], [C2000-204-37 C] before the passage enters Cave Tree Chamber.
There is a climb down of about 2m into Cave Tree Chamber, which has a bouldery floor on the left, and a pitch on the right [C2000-204-39 B]. An aven extends above [C2000-204-38 X], and the passage may continue over the pitch [C2000-204-40 A]. It would be advisable to protect this traverse.
