This mortarless stone arch bridge located near the Quabbin Reservoir was built in 1866. It's the only stone bridge that I can think of in Massachusetts (that I've seen).
means it has a larger influence on its environment than its abundance. It plays key role in maintaining the population of other animals in an ecological community.

Keystone species are those whose presence and role in an ecosystem is paramount to the point that they have a disproportionate effect on other organisms within the system. Ironically, though they have a lasting effect on the ecosystem, they are the least in count.
Who knew...they all matter!
Thank you for visiting.

A sweet-looking pair of CSX SD40-2s descend the West Slope of Sand Patch Grade on a fine Winter afternoon.
East Beckwith Mountain provides the backdrop in this view across an active beaver pond ringed with aspen in their brilliant fall colors. American beaver (Castor canadensis) are probably the best example of what ecologists call “keystone engineers,” a term used to describe an organism that impacts its environment disproportionately relative to its abundance. In other words, there aren’t a lot of beavers, but those few beavers have a huge impact on the landscape through their construction of dams. These dams alter the shape of valleys, increase the amount of standing water, and impact the abundance plants (such as the aspen) and animals that rely on greater water availability. The beaver dam and lodge for this pond are out of view to the right.
East Beckwith Mountain is part of the West Elk Range, formed principally by volcanic intrusions into sedimentary rock. A bit of fresh snow is visible on the north slopes, hinting that the beautiful fall weather and colors will soon be over.
Keystone Dam is located on the Arkansas River near Sand Springs, Oklahoma. Keystone Lake, above the dam is fed by the Arkansas River and the Cimarron River. Started in 1956 and completed in 1964, it provides electrical power and flood control for the Tulsa area.
This place looks more like a hunting lodge than a mine mess hall. The structure on the right end is the ruins of the shower house.

Alaska's Richardson highway passes thru this impressive canyon north of Valdez. A spectacular drive past major glaciers and stunning views. Shown here with 2 beautiful waterfalls: Horsetail (328 feet) and Bridal Veil (400 feet), flowing into the Lowe River.
Thanks for taking a look and for any comments, faves and suggestions!
As daylight begins to filter through the fog, an NS coal train rumbles through Keystone, WV, assisted by the Lehigh Valley heritage unit on the rear.
Deep gorge near Valdez Alaska, cut in the slate rock by the Lowe River.
In 2014 heavy snow (typical of the area) and avalanches completely filled this gorge in minutes, luckily no one was on the road at the time. The Lowe River was also blocked, and a new term was coined for the lake that flooded upriver from the 1500 foot long x 100 foot deep avalanche... a 'Damalanche.'
