Photo By Harry Lichtman Today’s Photo Of The Day is “Dressed in Winter” by Harry Lichtman. Location: Pemigewasset Wilderness, New Hampshire. “Expansive mountain views in New Hampshire don’t get much better, especially with a fresh coat of ice and snow to highlight the detail of trees, ravines and alpine scrub,” says Lichtman. “This view from Garfield Ridge encompasses Mount Washington (New England’s highest peak) on the far left and Mounts Bond, Bondcliff, Carrigain and Hancock in the Pemigewasset Wilderness as one pans right. Snow simplifies the chaos that’s often encountered when photographing such wide-angle views and allowed me to find compelling foreground elements in addition to the big peaks in the distance. Lower elevation snow rarely lasts very long as the deciduous trees are unable to hold snow effectively with the wind. The steel blue clouds provided just the right contrast to the mountains.” Want to get your images in the running for a Photo of the Day feature? Photo o...

Monticello is located on the northern branch of the Meduxnekeag River in Aroostook County, Maine, and is made up of about 38 square miles of rolling hills and beautiful farmland. Starting from a small pond to the west of Monticello, the Meduxnekeag River winds 35 miles through the scenic woodlands and pastures of Monticello before crossing the border into Canada, where it joins its confluence, the Meduxnekeag in Wakefield, New Brunswick. Once you get off of Interstate 95 in Houlton, take a left and drive 10 miles north, enjoying the potato fields in bloom during mid-summer or the crisp feel of the snow-covered landscape in the winter. An old rail bed provides access all over the county for more secluded views with miles and miles of ATV and snowmobile trails. Weather At Meduxnekeag River Summer in the county can get very hot and humid, with temps getting up into the 90s and dew points well into the 60s, making for some hot and sticky days.

Photo By Deena Sveinsson Today’s Photo Of The Day is “Van Gogh” by Deena Sveinsson. Location: Grand Teton National Park, Wyoming. “I had been trying for days to get a photo of a moose drinking water in the springs with a reflection of the Teton mountain range and moose,” explains Sveinsson. “I seemed to get every other type of photo but the one I had envisioned. This photo required the moose to enter on a specific stretch of water, on a certain side of the water, wanting to take a drink offshore and with no clutter, clear skies and a reflection. Tall order? Maybe I could get some water drips from his mouth? Even taller order. “We were duped by the moose that sat at the water edge that never went to take a drink. We were duped by a moose when they got up from their slumber only to walk in a different direction than his normal routine. On some days we waited all day in freezing temperatures but came back empty-handed. The reasons why I couldn’t get my dream photo goes on and on… “I...
