Maine's Baxter State park is home to streams, lakes, mountain peaks and wildlife. We meander down trails over lush green mossy banks and wander by picturesque ponds. Fungi and woodland creatures inhabit these 327 square miles of Acadian woods, which include the mighty Mount Katahdin.

We journey through some of the sites we visit this season -- from the black waters of Okefenokee to the soaring cliffs of Wadi Rum, on to the Venetian canals, the islands of New York and then from Iceland to Colorado's Gateway Canyon.

If you follow the eastward flow of fresh water from the Sierra Nevada mountains you will reach Mono Lake. The million year old lake possesses weird limestone towers called tufa. Photographers come from all over the world to capture the interplay of light on the mountains, desert, and water.

In 1132, thirteen Cistercian monks began building an abbey in northern England. They constructed a place for a simple life of devotion and contemplation. You can now walk through the atmospheric ruins that remain and gaze through a window into a way of life which shaped the medieval world.

With a depth of 800 feet, the Jokulsarion Lagoon is the deepest body of freshwater in Iceland. Seals are seen either swimming in the lagoon or lying on icebergs that are moving toward the sea. Freezing water laps against the black volcanic sands of the shore.

Nestled in the heart of Manhattan, against the backdrop of traffic and soaring skyscrapers, is the iconic Central park -- the most visited urban park in the United States. Designed by Frederick Law Olmsted and Calvert Vaux in 1858, the northern part of the park has a few lesser-known features.

A walk through a narrow canyon, or siq, leads to an ancient city spectacularly carved from the surrounding cliffs. You will never forget Petra, the seat of the Nabataean empire which thrived and then disappeared right around the time of Christ's birth.

Built in prehistoric Britain over the course of 1000 years, Stonehenge is one of the most famous megalithic monuments in the world. In the midst of the ancient, brooding stones on the plains outside Salisbury, you can feel the drama of their 5000 year existence.
