More caves with several narrow passageways. I picture these forcing medium sized characters to squeeze through. Small characters could negotiate without hinderance. The entrance is at the right. Following the wider passages forces characters to cross the crevasse. I figure this as a 5 to 10′ jump. Could be good to add some tension. Working through the upper caves and squeezing through the narrow passage at the top left avoids the crevasse for characters that search this route out.
At the upper left the final cave has a small passage the trails off. Was thinking this might lead to a hidden treasure in a small cave, or be a passage down to lower level.
