Logan Pass water system temporarily down
The water system will shut down Tuesday afternoon, July 22, and the temp system is anticipated to be working by the weekend. Visitors should bring water or refillable water bottles. There will be some water available to refill bottles in the parking lot. More »
St. Mary Visitor Center temporarily closed
It is believed that the furnace in the visitor center malfunctioned and caused the sprinkler system to activate early this morning. There is water damage to the building, its contents, and some of the utility systems. The damages are being assessed.
At least 127 non-native species of plants have either invaded or been deliberately introduced into the Park. Currently, over 800 sites of nuisance plant infestations impacting more than 2500 acres have been discovered. Routine monitoring by park biologists regularly reveals new infestations. Eighteen species of exotics plants are of sufficient concern to be targeted for control measures. The North Fork prairies are threatened by leafy spurge and yellow toadflax. Without the natural limitations of their original environment, exotic plants often tend to be highly prolific and develop a monoculture that is difficult or impossible to displace. Leafy spurge, for example, has a deep root system which is difficult to kill with even the most powerful chemicals.
Spotted knapweed and ox-eye daisy have invaded disturbed areas throughout the Park. Common timothy and other exotic grasses were introduced intentionally for horse grazing and unauthorized grazing of other stock within the park has spread nonnative weeds as well. Control measures have been only partially successful in slowing the spread of these infestations. Biodiversity among native plants is seriously threatened and only a major sustained effort will restore some of these systems.
Glacier Park's aquatic systems have been tinkered with for nearly a century, primarily through game fish introductions for recreational angling. This practice was was scaled back Lake trout, native to a few lakes in the Hudson Bay drainge of the park, have been introduced to several west-side lakes. The highly predacious foraging behavior of lake trout has had a catastrophic effect on native fish including the Federally listed bull trout. Further complicating the situation, introduced brook trout can hybridize with bull trout and produce sterile offspring. Introduced kokanee salmon and Lake Superior whitefish compete for food with native westslope cutthroat trout. Introduced rainbow trout also hybridize with the native cutthroat trout and corrupt their gene pool.
Full restoration of the native fishery in Glacier Park is impossible at this stage, but limited rehabilitation of native fish populations in some waters may be feasible. Partial recovery of native fisheries in the Park will come about only through further study, increased funding and aggressive management in cooperation with neighboring agencies.

If current trends continue, some scientists predict that by the year 2030, Glacier National Park will not contain any glaciers and many of the park's smaller glaciers will melt even sooner.
