Goshikinuma Pond Group

The Goshikinuma (lit., “colorful marshes”), are a cluster of about 30 ponds known for their turquoise, green, and copper hues. Around 300 of these shallow bodies of water formed following an eruption of Mt. Bandai in 1888. The eruption sent tons of debris cascading down the mountain’s northern slopes. The ponds formed in depressions that remained when the debris dammed several valleys.

The vivid, multicolored shades are believed to be caused by chemicals and mineral particles such as aluminum silicate in the water and sand. The colors are also affected by reflections of the surrounding landscape and differences in sediment and vegetation. Some of the ponds are very acidic, due to high levels of sulfates in the water, which is the result of the mountain’s volcanic activity. Some have a pH so low that they cannot support aquatic life.

Geologists believe water filters through to these ponds from lakes at higher altitudes. The Copper Pond (Akanuma) is a crater lake high on the northern slopes of Mt. Bandai. It is thought to be the source of springs that feed some of the ponds and affect their mineral content.

The 90-minute walk along the Goshikinuma Pond Trail passes 10 of these ponds.

五色沼湖沼群

以藍綠色、綠色、銅色等色彩而聞名的五色沼（意為「五光十色之沼」）湖沼群，是約30片湖沼的統稱。1888年磐梯山火山噴發，約300餘片大大小小的湖沼群隨之形成，五色沼湖沼群也在其列。火山噴發導致磐梯山北坡大量岩屑崩落。而在岩屑堵塞了數個山谷所形成的凹陷處，形成了這些湖泊和沼澤。2016年，五色沼湖沼群被評定為米其林綠色指南一星級佳景。

湖水因化學物質及水、砂中所含的矽酸鋁等礦物粒子，呈現出繽紛美麗的色彩。此外，湖水色澤同樣會被四周風景的映襯、沉積物或植被差異所影響。由於磐梯山的火山運動，使得部分沼澤硫酸鹽濃度升高，pH值過低，從而呈現出強酸性，導致水生生物無法存活。

地質學家們認為，這些沼澤會過濾自高地湖泊流出的水。

五色沼湖沼群

五色沼（意为“色彩纷呈之沼”）湖沼群是以蓝绿色、绿色、铜色等色彩而闻名的约30片湖沼的统称。1888年磐梯山火山喷发，约300余片大小不一的湖沼群随之形成，五色沼湖沼群也在其列。火山喷发导致磐梯山北坡大量的岩屑崩落。而在岩屑堵塞了数个山谷所形成的凹陷处，形成了这些湖泊和沼泽。五色沼湖沼群于2016年被评定为米其林绿色指南一星级佳景。

化学物质及水、砂中所含的硅酸铝等矿物粒子，使湖水呈现出艳丽而丰富的色彩。而四周风景的映衬、沉积物或植被差异同样会影响湖水色泽。由于磐梯山的火山运动，使得部分沼泽硫酸盐浓度升高，pH值过低，从而呈现出强酸性，导致水生生物无法生存。

地质学家们认为，自高地湖泊流出的水会被这些沼泽过滤。
