About Mount Katahdin

Climate of Baxter Park

The Park lies within the Northern Forest Region of the American Continent and experiences the cool, moist climate typical of this region. Climatic data from Caribou, Maine (70 air miles northeast) provides an overview of our seasons:

* Annual mean temperature: 38.6°F
* Record high temperatures: ~ 95°F
* Record low temperatures: ~ -45°F
* Average annual precipitation; ~ 37"(includes ~ 100"/year snow)

Summer temperatures and conditions peak in the Park in July and August. Fall colors begin to emerge in deciduous trees in the Park in early September and fall colors usually peak in late September or early October. Leaf-fall in deciduous trees is complete by the end of October. Lasting snowfall usually begins in mid to late November and lasts through April. In the Park, leaves emerge on deciduous trees around the last week in May. Weather in Baxter State Park can be characterized primarily by its variability; snowfall can occur any month of the year and temperatures can, and often do, fluctuate widely around the averages.

The Forests of Baxter Park

Baxter State Park as we know it today began to develop about 12,000 years ago as the Lauren tide ice sheet melted northward out of New England (Katahdin was once covered with glacial ice). Over the next 1,000 years the land that would become the Park developed a tundra ecology and the first human inhabitants left evidence of their presence. The following 1,000 years brought a steady emergence of forest growth:

"The development of the first forests in northern New England disrupted Paleo-Indian culture. Northern boreal forests of spruce and fir support relatively little herbaceous vegetation, and therefore offer little subsistence for gregarious herbivores like the caribou. Some of the large herbivores, such as musk ox and caribou, remained on the tundra, drifting gradually northward out of the region. Many other species simply died out, no longer able to find enough forage." 1

Over the ensuing 8,000 years as the climate gradually warmed, the forests of the northern Maine developed from the boreal forests now found further to the north to the spruce and fir dominated "Acadian" forest. This forest is characterized by poor or moderately drained soils, over compressed glacial till or areas of shallow soil over bedrock (Leak and Riddle, 1979). U.S. Department of Agriculture Bulletin 544 of 1917 offers a description of the earlier Park forests:

"....Spruce, birch, soft maples, white pine, hemlock , and balsam are the characteristic trees in mixture...The presence of black ash, which is usually accompanied by considerable balsam, denotes conditions bordering on the swamp type. The presence of sugar maple, on the other hand, denotes a transition to the hardwood lands. White pine of good quality formerly occurred in abundance in this type in both Maine and the Adirondacks... Spruce attains an intermediate development here, while birch and the better hardwoods are inferior in development as compared with the same species growing on the hardwood lands.....Windfall is not uncommon, and as a result young even-aged stands of spruce are found occupying the ground where this has taken place...".

A landmark study by Ralph S. Hosmer in 1902-3 in a Greenville area Township described a tract of "virgin forest" of 20 acres (even by the 1900's unharvested forest was rare) on sites similar to Baxter State Park. Over ninety percent of the stand was composed of 5 species, red spruce (65.4%), yellow birch (14.3%), sugar maple (5.7%), paper birch (4.1%) and balsam fir (2.7%).2 The maximum diameter of spruce measured on the site was 27 inches. In most respects, this description would probably apply reasonably well to the forests of Baxter State Park around the start of the nineteenth century. Without question, human action over the ensuing decades has altered the forest mosaic in many ways.



The nature of Baxter Park

The Park is home to numerous mountains, the two most notable clusters being the peaks comprising and surrounding the Katahdin massif and the cluster of peaks in the northern part of the Park consisting of the Traveler Range. Pink and white Katahdin granite make up the rugged mountains on the southern end of the Park while the Traveler range further to the north is composed of Rhyolite with prominent columnar jointing visible in many places. The north end also features sedimentary rock in certain localities. Glacial features are abundantly evident throughout the Park in the form of kettle ponds, eskers, moraines, erratics, the Knife Edge arête, the glacial cirques of Katahdin and the splendid U-shaped valley running north to south from the Travelers to South Turner.

The mountains combine with a wide array of ponds, lakes, streams, waterfalls and bogs to create a varied and beautiful landscape. Favorite waterfalls include Katahdin Stream Falls, Big and Little Niagara Falls and the remote Green Falls. Two of the most significant streams are Nesowadnehunk Stream and Wassataquoik Stream. Ponds such as Kidney and Daicey Ponds, Grassy Pond, Rocky Pond and the Fowler Ponds, among many others, provide excellent fishing in most cases and the chance to canoe with friends and family with the scenic north woods as a backdrop. We have numerous bogs with the associated plants, birds and wildlife unique to such areas. In the forested areas, wildlife includes moose, deer, bear, otter, mink, marten, fisher, weasel, coyote, bobcat, beaver, muskrat, raccoon, woodchucks, snowshoe hare, squirrels, chipmunks, flying squirrels, mice, voles, lemmings. Avid birders enjoy the variety of environments found in the Park, resulting in sightings of many different wood warblers, thrushes, and flycatchers as well as game birds, several species of owls and hawks, and many ducks and other wetland birds. Amphibians and reptiles are representative of freshwater habitats throughout northern New England and provide our young campers some engaging encounters. Insect life is abundant and diverse, including some beautiful beetles, dragonflies and butterflies, however, the insatiable black fly seems to have achieved the greatest notoriety in the memories of some of our campers!

The plant life in the Park is as varied as the terrain and wildlife. From wetland plants to woodland ferns and wildflowers to alpine plants, the regular Park visitor will find a plant guide to be very useful. However, the plants that are sure to be most popular with most summer visitors are the blueberries, raspberries and blackberries. Just remember to check the other side of the bush to find out if a resident black bear has prior claims on the bush!

Baxter State Park was originally conceived as a park "for those who love nature and are willing to walk and make an effort to get close to nature"3 Unlike some parks which are designed to display the area via auto access, with groomed viewpoints along the road and convenient travel by automobile, the features and diversity of Baxter State Park are best seen on foot. The Park was designed primarily to be a hiking park with vehicular access on the limited and very primitive road system intended not as a means to thoroughly experience the wilderness but only as a way for visitors to reach their starting point, . There are approximately 200 miles of trail maintained by the Park. These trails range from the heavily-used boardwalks around Sandy Stream Pond to the remote and little traveled Freezeout and rugged Northwest Basin Trail. There are moderate trails around ponds, pleasant trails to waterfalls and challenging boulder-strewn pathways up many of our mountains. All these trails must be marked, brushed out and repaired regularly by BSP's Trail Crew. Each season roughly 10 people, usually volunteers from the Student Conservation Association, along with the Trail Supervisor and two BSP Trail Crew Leaders, undertake this task. They are joined each summer by dozens of individuals who volunteer either as a group or alone to contribute their time and effort to maintain quality trail access to this Park.




The Park was designed by Park donor Percival P. Baxter to preserve the Park in its natural state. All of the Parks geological features, animals and plants, such as mentioned above are, by regulation, to be left in the Park, undisturbed for their own sake and for the enjoyment of future visitors. Of course, harvesting berries and fern fiddleheads for personal consumption and catching fish according to the state regulations for the particular body of water you are fishing are all permitted within the mandate of the Park. Just a note of interest: throughout the Park, hikers may stumble upon the remains of old lumber camps or settlements. While preserving human artifacts is not a management priority, cultural objects are also protected from collecting. Objects such as wood stoves, old kitchenware, old tools, horseshoes and other items should not be collected but should be left where they are found, so that Park visitors discovering them might be able to reflect on the history of the Park's land, passage of time and the regenerative power of nature. We expect all visitors to practice low-impact camping and hiking in this wilderness area. We hope you enjoy the diversity of settings and life found in this beautiful gift former Maine Governor Percival P. Baxter so generously gave to the people of Maine!
