The study is being conducted by consultants from Edmonds, Washington.
It stretches along the Gulf Coast for about 50 miles and reaches inland about 30 miles. It is visible on a clear day from Ocean Cape. The Yakutat Glacier is one of the largest glaciers in the forelands and it feeds into Harlequin Lake and forms the headwaters of Dangerous River.
This lake, river, and glacier are accessible via Forest Highway Perhaps the best known glacier in the Yakutat area is Hubbard Glacier.
The persistent advance of this glacier since about has generally accelerated during the 20th century and has led to its great notoriety. The advancing ice and push moraine blocked the entrance to Russell Fiord for the first time this century near the end of May The level of water in the Fiord began to rise immediately because of fresh-water inflow from Hubbard Glacier itself, as well as other glaciers and non-glacier areas surrounding the fiord.
This dam caused Russell Fiord to become Russell Lake, creating the largest glacial dammed lake in the world.
The dam, however, gave way between The outburst flood swept away the ice and moraine dam, as well as most of the loose sediments that had nearly connected Osier Island with the mainland.
Island with the mainland. If the dam had not failed, water would have eventually over flown into the Situk River, causing it to increase by approximately fold. This increase would dramatically alter the fisheries and recreational characteristics of the Situk River, thus greatly impacting the Yakutat economy, salmon fisheries, wildlife, cultural resources, ground water, vegetation, and the area's transportation systems.
In spite of this, preliminary estimates indicate that not all effects would be negative in the long run. During the spring ofa surge in Hubbard Glacier was observed once again.
This event was judged to be similar in magnitude to the event that resulted in the damming of Russell Fiord. The reason the surge did not result in a closure was that the loose materials forming the protective moraine that reduced calving in had been washed away by the outburst flood.
At the present rate of advance, the terminus at Sand Dab Passage should have reached Gilbert Point by about Unpredictable events, however, make such a simple forecast unreliable. Analysis of recent glacier behavior and current conditions indicates that a closure which eventually results in overflow into the Situk is likely to occur within the next decade.
Hubbard Glacier is in the strongly advancing phase of the calving glacier cycle and is likely to continue regardless of climate variations, although the gradual increase in both annual precipitation and temperature recorded at Yakutat since does favor glacier growth. A spring closure will, however, be subject to the most rapid water-level rise as both melt and rain runoff fill Russell Fiord.
A rapid rise of the lake could outpace the thickening and widening of the dam due to ice flow and thus increase the likelihood of dam failure. The more time that passes before the next closure, the more likely the closure will last long enough to produce an overflow into the Situk River drainage.
As time passes, the general advance of Hubbard Glacier terminus will result in a stronger dam due to the greater thickness of ice. Considering the complex interaction of dam formation and failure processes, it is likely that overflow into the Situk drainage may be episodic at first, as dams form and fail.
However, once a stable dam is in place, it is likely to be sustained for many hundreds of years as Hubbard Glacier slowly advances down Disenchantment and Yakutat Bays during the advance phase of the tidal glacier cycle.
There is a small chance that a closure will not occur in the next 10 years, and an even smaller chance that a closure may be forestalled for decades. For instance, it is possible that the advance into Disenchantment Bay will partly bypass Gilbert Point, and a tidal channel will be maintained temporarily.
Less likely, the closure could be forestalled by a calving retreat in Hubbard Glacier. Generally, the old-growth forest is extremely dense and impenetrable.Overview: Strange as it may seem, Ohio has an isolated colony of Plains gartersnakes.
These brightly marked gartersnakes occur only in Marion and Wyandot counties, in the vicinity of the Killdeer Plains Wildlife Area, where they inhabit remnants of what was once the most extensive wet prairie in Ohio.
Gray Lodge's diversity and location along the Pacific Flyway make it a haven for wildlife. Surrounded by miles of rich agricultural lands, the approximately 9,acre area is managed for the wildlife that call Gray Lodge home for all or part of the year.
