The right side of the icefall is some 50 metres high, and the width varies from year to year. The brook that creates the ice originates on the slopes of Yli-Voho Hill. Most of the brook's clear water comes from a spring, which gives the ice sheet its distinct blue colour.

An ice wall in the middle of an uneven cliff face. There are trees both on top and at the foot of the cliff.
Ruskea virta at Piippukallio is Korouoma's largest and highest icefall. As the highest frozen waterfall at Korouoma, it poses a challenge even for more experienced ice climbers. The middle area routes rise to about 60 metres. The water flow is strong all through the winter, and if the frost sets in early, you can go climbing at the turn of October and November. The last pieces of ice usually disappear at the turn of May and June.
- Height of the wall: about 35-60 metres

You should not climb under the frozen waterfalls, as ice blocks and stones can detach and fall from the falls. It is advisable to watch ice climbers from a distance for this reason.
