"A stick in time: After quickly turning a sapling into a shovel handle, one firefighter attacks with sand while another beats the flame with birch branches. If smokejumpers kill a fire quickly, it adds a bonus to their monthly hundred-dollar pay."
—From "Russian Smokejumpers," August 2002, National Geographic magazine

Where: Hudson Bay, Canada
When: 1996
Photographer: Flip Nicklin
"Most [female polar bears] keep their young [such as the cub at the bottom in this picture] with them for two and a half years, but many Hudson Bay mothers wean their cubs a year earlier. That allows them to breed every two years instead of the usual three. Perhaps the large number of seals at Hudson Bay influences this fecundity. The abundance of seal carcasses left on the ice might make it possible for young bears to scavenge at an earlier age and become independent sooner."
