I spent a week home in Cork, and got two decent days in the mountains done. The first was an ascent of Knockboy, the highest point in Cork, in a very wild and beautiful part of the country just on the border with Kerry. Like most Irish mountains apart from the most well known, there is no marked path and the going is extremely boggy. It seemed to be a bright day, and I had great views down to Glengarrif by the sea on one side, and over the Kerry mountains on the other. I didn’t have a compass with me, but didn’t think much of it as I headed up the road and turned off over a stile to start up the mountain.
I was moving quite well over the bog, and could see the trig point at the top where I was headed, I knew it was at about 800m, and I chose to run along a fence line as it skirted the worst of the bog. It started to get cold, but I had a jacket in my pack. Suddenly, within a few minutes, the clouds closed in. I was extremely lucky I had decided to stay on the fenceline as I could no longer see anything more than 5m around me. The world had shrunk into whiteness and it was now very cold. I stuck to the fence and using the navigation app on my phone (ViewRanger), I got to the trig point at the summit.
Now it was time to go back. I followed the fenceline back down the way I came, then got to a lake, which I could identify on the map. At this point I decided to try to navigate back to the road, but as soon as the lake was out of sight, all landmarks simply vanished. I had no idea which direction I was moving, my phone wasn’t much use, and the compass on my watch told me where north was, but not how to get through the maze of bog I now found myself in. The whiteness was disorienting and eerie, and I was moving so slowly it was hard to stay warm. I decided to climb up a hillock to try to get onto firmer ground. Suddenly, as quickly as it came in, the clouds cleared. I could see the road! I could also see that I had been headed in exactly the wrong direction.
Lesson learned. Mountains, even small ones, are very dangerous. If I hadn’t had my jacket with me, and the mist hadn’t cleared when it did, this could have been a very scary experience. It had been warm and bright at sea level, a good 21 degrees and clear sunshine. It was probably 15 degrees colder on the hill, windy, and all landmarks completely invisible. Always bring a proper compass and map. Don’t rely on technology. Bring warm clothing, gloves and extra food. You just never know.
