Maszynka do Mięsa, couloir in the Tatra Mountains, Bukowina Tatrzańska, Poland

Maszynka do Mięsa is a large couloir dropping from the lower part of Bańdzioch to Szeroki Piarg above Morskie Oko in the Polish Tatras. Between its throat and Bańdzioch lies a gravel-and-grass cirque enclosed on three sides by walls about 30 m high, fed by two usually water-poor waterfalls. Below the cirque the streams join into a 40 m waterfall plunging through the couloir.

The couloir's climbing history is documented by Władysław Cywiński, who warned that it is highly avalanche-prone and should be avoided in bad conditions. Two climbing routes exist, both for tatra climbers only: one from Wielki Piarg through the couloir, rated 0 in the Tatra scale with about 170 m of denivelation and 30 minutes, and one through the icefall in winter at an angle of 80–90 degrees. In summer the lower part, up to the fork with Żleb Ratowników, has never been climbed because of its steps and waterfalls.

The name, meaning "meat grinder", comes from the couloir's shape: a narrow gully that funnels everything falling from the northern walls of the Mięguszowieckie Peaks. In winter the two upper waterfalls and the lower one freeze into icefalls where climbers train, but the same channel carries snow and rock avalanches, as on 5 August 2001, when a rock avalanche reached the shore of Morskie Oko and left a 2 m high, 12 m wide stone rampart across the tourist path.

The couloir is climbed only in winter; in summer its lower part, up to the fork with Żleb Ratowników, has never been ascended because of its steps and waterfalls. Two climbing routes exist for taternicy only: from Wielki Piarg through the couloir (0 in the Tatra scale, about 170 m of denivelation, 30 minutes) and through the icefall (80–90°). Władysław Cywiński warned it is a very avalanche-prone place and should be avoided in bad conditions.

The couloir is the exit of a huge depression beneath the Mięguszowieckie Peaks, so water, snow avalanches and rockfalls from their north walls all funnel through it. A rock avalanche on 5 August 2001 reached the shore of Morskie Oko and buried the tourist trail under a 2 m high, 12 m wide stone bank; no one died because heavy rain had kept tourists and climbers away.
