Officials cited rockfall danger and traffic hazards created by people stopping to fill containers.
In what researchers describe as the largest study of its kind, scientists have found new evidence of a link between infection with the protozoan parasite, Toxoplasma gondii, and schizophrenia.

Fisheries and Oceans Canada confirms the findings of independent research that says sea lice on salmon farms are becoming resistant to SLICE, a pesticide used to kill sea lice.
Researchers examined 179 radio-marked young moose over the course of a four-month period. Of those calves they screened, 125—or nearly 70 percent—of the moose calves died. The researchers suspect this is primarily because of the winter tick.
The news isn’t getting any better for New Hampshire’s moose, as the population explosion of winter ticks driven by warmer winters continues to take a toll.
A new project will test ticks found in Alaska to see if the tiny, blood-sucking arachnids carry the pathogens that cause Lyme disease, tularemia or other illnesses.
Water quality in Anchorage's lakes is generally good, but swimmer's itch is a risk.
Every year, billions of animals migrate across the globe, carrying parasites with them and encountering parasites through their travels.
Serious and unusual outbreaks of illness from eating raw or undercooked walrus to call attention to the risks.
Wild salmon from the Pacific coast of North America may be infected with Japanese tapeworms, according to a study in a CDC-published journal.
B.C salmon farms last year were besieged by sea lice, according to a new University of Toronto study, which also found a dangerously steep rise of infestation among young wild salmon who swam nearby.
A recent study shows that polar bears' mercury levels are declining as melting ice drives them onshore. But is it all good news? Read on.
A parasitic isopod that scientists identified five years ago has all but decimated mud shrimp populations in coastal estuaries ranging from British Columbia to northern California - with the exception of a handful of locations in Oregon from Waldport to Tillamook.
Worms infecting fish grow four times faster at higher temperatures and manipulate the behavior of fish.
Data cited by the B.C. Centre for Disease Control suggests 75 per cent of wild Pacific salmon are infected with the parasite. If fish is to be consumed uncooked, killing the parasites requires it to be frozen at -20 C for at least a week, Young said. Most commercial sushi-grade seafood suppliers freeze at -40 C.
Idaho’s most controversial predator could play a role in managing the spread of a deadly deer and elk disease, according to a leading research scientist.
“This is unprecedented in the United States for a mature, rationalized fishery to suffer a stock collapse, in part due to climate change,” the executive director of the Alaska Bering Sea Crabbers said.
Due to anticipated continued increased temperatures, Finland's inland fishing problems are likely to continue.
