1. Coastline — ONP's coastal strip is a rugged, often fog-enshrouded stretch of sandy beach and a small area of adjacent forest. There are thick groves of trees that march right up to the sand, which results in chunks of timber from fallen trees that litter the beach. Interestingly, the small coastal portion of ONP isn't even connected to the much larger, main portion of the park. President Franklin Delano Roosevelt had intended for them to be connected via a continuous strip of park land, but political forces decided otherwise.
2. Glaciated mountains — Within the center of ONP rise a series of mountains whose sides and ridgelines are topped with massive, ancient glaciers.
3. Temperate rainforest — The western side of ONP sports a temperate rain forest, the wettest place in the coterminous United States (the island of Kauai in the state of Hawaii gets more). Because this is a temperate rainforest, as opposed to a tropical one like the Amazon Rainforest in South America, it isn't dominated by tropical ferns, but rather contains dense timber, including spruce and fir, and mosses that coat the bark of these trees and even drip down from their branches in green, moist tendrils.

Natural History

Because ONP sits on an isolated peninsula, with a high mountain range dividing it from the land to the south, it developed many unique plant and animal species (like the Olympic marmot and Roosevelt elk) that can't be found anywhere else in the world. Because of this uniqueness, scientists have declared it to be a Biological Reserve, and study its unique species to better understand how plants and animals evolve. A good book about the natural history of the region is Olympic National Park: A Natural History Guide by Tim McNulty.

Human History

Prior to the influx of European settlers, ONP's human population consisted of Native Americans, whose use of the peninsula consisted mainly of fishing and hunting. When settlers began to appear, the use of the peninsula (as with much of the Pacific Northwest) shifted toward harvesting of timber, which began heavily in the late 1800s and early 1900s. There wasn't much dissent against the logging until the 1920s, when people got their first glimpses of the clear-cut hillsides where trees had been logged. (The 1920s saw an explosion of people's interest in the outdoors; this occurred because the automobile allowed people to tour previously-remote places like the Olympic Peninsula.) Public desire for preservation of some of the area grew until President Roosevelt declared ONP a national park in 1938. Even after ONP was declared a park, though, illegal logging continued in the park, and political battles continue to this day (including President George W. Bush's declaration that logging restrictions must be eased) over the incredibly valuable timber contained within its boundaries. A good book detailing the history of the fight for ONP's timber is Olympic Battleground: The Power Politics of Timber Preservation by Carsten Lien.

Recreation

There are several roads in the park, but none penetrate far into the interior. The park features a network of hiking trails, although the size and remoteness means that it will usually take more than a weekend to get to the high country in the interior. The sights of the rain forest, with plants run riot and dozens of hues of green, are well worth the certainty of heavy rain sometime during the trip.

A nearly unique feature of ONP is the opportunity for backpacking along the beach. The length of the coastline in the park is sufficient for multi-day trips, with the entire day spent walking along the beach. Although idyllic compared to toiling up a mountainside, one must be aware of the tide; at the narrowest parts of the beaches, high tide washes up to the cliffs behind, blocking passage. There are also several promontories that must be struggled over, using a combination of muddy steep trail and fixed ropes.

If a natural water source is available

• Water may be boiled over a campfire or portable stove. At high altitudes, water boils at a lower temperature, so the boil must be maintained for several minutes to kill the microorganisms.
• Water may be filtered with a portable water purification device. Water purifiers differ widely, so if you own one, familiarize yourself with the instruction manual. If the water is visibly dirty, pour it through a cloth to remove large particles and avoid prematurely clogging the purifier.
• Certain chemicals, such as dilute chlorine solution, are commercially sold as antimicrobial additives. Some leave an unpleasant flavor that may be masked with powdered drink mix.

Probably the best way to get water from the ground is the evaporation still, shown in cross-section in the diagram at right. To build an evaporation still, you need only four items: a shovel, a sturdy sheet of transparent plastic, a cup, and a piece of flexible plastic tubing long enough to reach from the middle of the plastic sheet to the side with some excess length.

Begin by digging a hole with sloping sides in the shape of the sheet of plastic, but slightly smaller. Avoid digging in hot weather, as you will lose considerable amounts of water through sweat. Sink the cup in the middle of the hole so that the rim is almost flush with the sides of the hole. Place one end of the tube in the cup, run the other end to the outside of the hole, and place the sheet of plastic over the whole assembly. Weigh down the sides of the plastic sheet, or anchor them with stakes, and place a small weight directly over the cup.

The evaporation still will produce water continuously. The plastic sheet will create a greenhouse effect in the still, accelerating the natural evaporation of water from the soil. When the water vapor hits the plastic sheet, it will condense and drip down into the cup. The tubing may be used to drink from the cup without disturbing the still. For added effectiveness, use a second cup to pour any available fluids, such as urine, into the pit.

The vegetation still

The water in the bag will pick up chemicals from the leaves. These will give it a strong leafy flavor, and may include toxins, so make sure not to gather any poisonous plants.
