Traced from the cave-ha.com Monkey Dust cave lines map (Alex Vronsky 2024 lines over the Nadia Bernie survey, 150 ft scale bar); the dense western network is simplified to its main lines and small loops are left out. The permanent line starts a bit left of the wooden platform; at the first T the right-hand line runs north toward Sistema Dos Pisos and the left opens the Monkey Dust area (cave-ha.com). A dive-centre whiteboard in the owner's notes gives about 9 m (30 ft) at the first T and an average of 10–12 m. The pool outline and the entrance position are approximate, as are all positions.
Monkey Dust is one of the five ways into Sistema Dos Pisos, alongside Balam, Dos Pisos, Dos Pisos Norte and Zooz.
Four dives between March 2025 and February 2026, maximum depth 9.1 m — and one of 230 minutes. Three hours and fifty minutes is the longest single dive anywhere in this log, and it is possible only because the cave is shallow enough that the limiting factor is gas and cold rather than decompression.
