The mountains (or hills) were hiked from March 27 to June 4, 2013. These were all day hikes—anywhere from 1 to 4 mountains per day. The official list came from the Korea Forest Service, from a study they did from 2006-2007.
The soil was borrowed at the end of the hikes, and always at the bottom of the mountains. No soil was taken from the peak, near temples, in the forests, on the trails where people walk on, or from what looked like the city’s gardening projects. In some special cases, I had to borrow from the nearby parking lot, or near the official mountain entrance. This was for several important reasons: some of these mountains are considered holy in Korea, or are national parks where it is illegal to take or leave anything. It’s also not a good idea to be carrying heavy soil in your backpack on the way down a dangerous mountain. I looked for little spots that seemed overlooked and “unimportant,” then started to dig some soil to place in small jars. The volume capacity of each jar was 500 mL.
The plants used were bought from my neighborhood market in Seoul. I chose local plants that were strong and can withstand the stress of being planted and exhibited indoors, to being transferred and planted in the mountains.
According to MyTracks, the app I used, I hiked 124 kilometers (about 77 miles) for a total of 60 hours.
