Yesterday, the Visitor Center held a course and marshland walk titled “Kogen Onsen-numa Route.”
The area of the walk is popular with climbers during the fall foliage season. The cluster of ponds was formed when landslide material from Takanegahara became deposited there and then subsided over many, many years. Water filled the resulting depressions to form more than 100 ponds.
The numerous ponds of various sizes seemed to form a shape resembling an open folding fan (ogi in Japanese) when they were first discovered, and therefore this location was called “Ogigahara.”
The area was discovered in 1916. The forest road there was built as part of work to deal with trees knocked over by the “Toya-maru Typhoon” of 1954 and later extended to the hot spring area. The Daisetsu Kogen Onsen Hotel was built in 1963. The discovery of the Kogen-numa area was noted on a surveyed topographical map in 1926, and the walking course around the ponds was completed in 1961.
Over 150 species of plant can be seen in the area, among them Hypericum yojiroanum, which is a plant specific to the Daisetsu area, and Viola epipsiloides, which is a plant specific to Hokkaido.

The Akaishi River is a little high today, enough to splash on to hiking boots.
The rocks are somewhat slippery, so it is best to take care when crossing and to have the proper equipment. It is also a good idea to check if rain fell the previous day before setting out.
Communities of Primula cuneifolia var. cuneifolia and Phyllodoce aleutica are forming nearby.
The Diapensia lapponica subsp. obovata, Loiseleuria procumbens, and other plants are also flowering where the snow has melted.
In the area of the Hokkaisawa Stream, it is possible to spot small communities of Sieversia pentapetala and Phyllodoce caerulea.

Although the Sieversia pentapetala and Phyllodoce caerulea are still forming communities in the distance, the Sieversia pentapetala have become cottony in most areas.
Mixed in among them are Potentilla matsumurae, Primula cuneifolia var. cuneifolia, Solidago virgaurea subsp. leiocarpa, and Gentiana nipponica.
Flowering seems to be ending for the Therorhodion camtschaticum on the peak and Bryanthus gmelinii near Ishimuro. The scene appears to be being set for autumn.

Some flowers are starting to wilt, perhaps as a result of the recent heavy rain. Nonetheless, from the 8th Station up to the peak, the Hypericum kamtschaticum shown in the photo, Trollius riederianus, Filipendula camtschatica, Solidago virgaurea subsp. leiocarpa, and other flowers create vibrant scenes along the trail.
Additionally, the Aconitum yamazakii, Parnassia palustris var. palustris, and other autumn flowers are starting to become noticeable. Mt. Kurodake’s “mountain of flowers” look continues.

On the Mt. Aka course trail, a snowy gorge of some 32 meters remains in the upper area of Daisan Sekkei. While the distance to be traveled over it has shortened, the surface has become firmly packed. Care is required when ascending and descending. At Daini Kaen, a snowy gorge of roughly 67 meters remains. However, a rope is firmly in place and the grade is not as steep as at Daisan Sekkei, so it should not present a major problem to climbers.
The snowy gorges that remained on the trail at Daiyon Sekkei and Daiichi Kaen have almost completely disappeared as a result of the recent heavy rain.
