It is nature, human and animal imprints that interests him.
The tracks we leave behind us and the tracks that nature leaves. Details that might go unnoticed and perhaps are gone shortly after they were there. Changes in nature that constantly occurs during the seasons, hiding preceding the events. The stillness of nature and the environment, events that occur all the time, but so slowly that we do not see them.
Marvel at the power of nature to reclaim and break down.
