Location
In a forest close to Tervasuontie road, easily accessible.
Participants
Plans
I planned to visit the point by cycling from Joensuu, the distance would be about 20 kilometres in one way. The weather should be perfect: partly cloudy and 0 °C in the afternoon.
Expedition
It took me until about four o'clock to leave from home. Almost all roads were clear of snow, and so I could cycle easily. The temperature had decreased to −1 or −2 °C and continued to decrease slightly. I visited a few geocaches along the way, including one at a lean-to (location 62.59926°, 30.03140°; GC5H0TQ) where I took a longer break. Eventually I got near the hashpoint where I had to walk the last eighty metres.
The hashpoint was in a depression, a very common (in this part of the world, at least) terrain feature created by a melting block of ice at the end of the last ice age. It was elliptical in shape, twenty to thirty metres in diameter and two or three metres in depth, and the edges were rather steep and clearly defined. There was a thick layer of snow at the bottom, and I could literally walk on it. This is known as crusted snow, and it forms when snow melts and freezes repeatedly, eventually creating a hard surface layer that can support a walking person. I do not feel like this should count as a Water Geohash though.
After leaving the hashpoint, I visited a few more geocaches. I finally got home at about nine o'clock, by which time it had got dark. The total cycled distance was 49.2 kilometres.
