convenient campsite to house hunting and fishing parties. The earliest of these shelters were quickly and crudely built but they still offered shelter from the elements. As the Adirondacks developed, so did the lean-to structures. The previous temporary structures were replaced by sturdy log structures. Made from what was available, balsam or spruce logs were commonly used. Cedar has replaced these species as the primary log, due to its natural rot resistance and easy workability. Some High Peaks lean-tos do not have fire rings in front of them. Boofen An even simpler shelter is found in the Elbe Sandstone Mountains of German-speaking Saxon Switzerland where climbers refer to overnighting in the open air as Boofen (pronounced "bo-fen"). The spot selected for overnight stays usually comprises an overhang in the sandstone rock or a cave, the so-called Boofe ("bo-fe"). This has often been adapted with a sleeping area and fireplace. In the national park itself, Boofen is only permitted at designated sites and only in connection with climbing, although in this case lighting fires is absolutely forbidden. The colloquial Saxon word boofen was derived from pofen (= sleep soundly and for a long time). Huts by country Finland Official wilderness huts are mostly maintained by Metsähallitus (Finnish for Administration of Forests), the Finnish state-owned forest management company. Most of the wilderness huts in Finland are situated in the northern and eastern parts of the country. Their size can vary greatly: the Lahtinen cottage in the Muotkatunturi Wilderness Area can barely hold two people, whereas the Luirojärvi cottage in the Urho Kekkonen National Park can hold as many as 16. A wilderness hut need not be reserved beforehand, and they are open for everyone tracking by foot, ski or similar means. Commercial stays overnight are prohibited in the wilderness huts owned by Metsähallitus. Unofficial and unmaintained huts also exist. For centuries the vast wildernesses of Finland and its resources were divided amongst the Finnish agricultural societies (such as families, villages, parishes, and provinces) for the purpose of collecting resources. Areas divided in this way were called erämaa, literally "portion-land," (now literally the word for "wilderness" in modern Finnish). People from agricultural societies made trips to their erämaas in the summer, mainly to trap animals for fur but also to hunt game, fish, and collect taxes from the local hunter-fisher population. Huts were built in the wilderness for use as base camps for
