Description:
Swecker Cave is entered by a short, tight crawl which leads into a small, sparsely decorated room. A blowing hole in the floor was dug open to reveal another short crawl with a nasty "S"-bend constriction. Beyond this corkscrew maneuver the cave's dimensions begin to unravel. A balcony is quickly reached overlooking a large room. A 25' drop rigged from a convenient boulder lands a visitor in a 45' wide, 30' high trunk passage, leading southeast for over 600'. The first 200' is floored with football-sized breakdown, but the remainder is flat, mud-floored and generally free of broken rock. Green flagging tape follows the preferred route through this impressive strolling borehole. The passage is liberally decorated with speleothems. Near the end of the borehole the floor formations require the visitor to concentrate on where the trail is.

There are few significant side passages until reaching Amphipod Alley, where a climb near the Broomstick Bypass leads to a abandoned upper-level infeeder. Originally, the trunk passage suddenly pinched down to an extremely windy lead four feet wide and three to four inches high. A muddy trench was excavated over 100 feet to open into a continuation of the borehole.

The borehole was found to continue for only 300 feet. However, a canyon leads to an intersection with a stream passage. The stream goes downstream for 200 feet as a hands and knees crawl ending in breakdown. Upstream, the cave continues on two levels for over 1,000 feet with an occasional speleothem. The water issues from a narrow joint and breakdown not far from it's surface sink point.

Swecker Upper Decker
This is a short section of passage developed along the same fault seen in the trunk passage in Swecker Cave. The fault cuts diagonally through the strata and Swecker Upper is located above and slightly to the east of Swecker Cave. The map profile view at 30° shows this relationship quite well.

A tight crawl in a shallow sink leads to a hallway 300 feet long. A few crevice drains in the floor probably lead to Swecker Cave but are too narrow to follow. To the southwest is pleasant walking passage which ends in breakdown. It could probably be extended in that direction if there were any point. Travelling north from the entrance a pit to nowhere is encountered. Walking past a few nice formations will reveal the end of the cave, not too far from the Swecker sink.
