The glacial landforms are an important part of the landscape in Pelister National Park. Within the boundaries of the Park there are three fine examples of cirque fields two of which contain lakes. The most spectacular is the cirque between the peak Veternica and the R’bet ridge, having north-east exposition, some 1.0 km in width and 1.6 km in length. In the westernmost part of the cirque, lays the Greater Lake. The second, the Smaller Lake, lays in the cirque situated between the peaks Shiroko Stapalo and Partizanski. During the Würm glaciation period the glaciers were hanging over the shoulders of Pelister Mountain. The block streams are most prominent among the periglacial landforms in Pelister National Park. They typically extend from above the forest margin down slope to 1.200 m above the sea level; some of them are more than 2 km in length and between 100 and 300 m wide. This feature is indicative of their high activity during the Pleistocene epoch (1.8 million to 8.000 years ago). Although the block streams in the Park are still active, many of them have been overgrown by the quickly expanding molika forest. To the north-east of the peak Pelister (2.601 m) and towards the peak Stiv (2.468 m) is found a typical block field – a periglacial form of frost-shattered granite blocks, scattered over a slightly bent area. Other glacial and periglacial landforms in the Park include nivation hollows, garlands, solifluction lobes, and ploughing blocks. The latter consist of Paleozoic alkaline granites and can be found on the eastern, north-eastern and the northern side of the massif. Typical examples of the ploughing blocks are found in the cirque of the Smaller Lake.
