A blue coloured semicircle painted onto the ice where a goaltender positions himself during a game. The straight line edge of the semicircle-shaped goal crease is the red goal line, which covers the width of the ice surface. The goaltender's net is placed along the portion of the goal line that is common to the semicircle and to the red line extending the width of the ice.
An NHL ice surface contains two goal creases, one at each end of the rink. Both goal creases are directly opposite each other. In the NHL, the semicircle that makes up the goal crease has a radius of 6 feet (or 1.83 metres) and a width of 2 inches (or 5.08 centimetres).
Up until the 1999-2000 NHL season, if a team scored a goal while one of its players had his stick or any part of his body in the goal crease, the goal was disallowed. The most famous incident involving this former rule occurred during the 1999 Stanley Cup finals between the Dallas Stars and the Buffalo Sabres. During the third overtime period of the sixth game of the finals, Stars winger Brett Hull appeared to clearly have his skate in Sabres goaltender Dominik Hasek's crease while scoring a goal. However, the referees did not call off the goal, and because the Stars were up three games to two in the series, they won the Stanley Cup as a result of that controversial goal.
