The search process includes four phases: the signal search, the
coarse search, the fine search, and the probing/pinpointing phase.
Signal Search: The signal search refers to the process of
establishing a search pattern and looking for a signal. The search
pattern will be defined by the victim’s last seen area, the size of the
slide, and the number of searchers. Refer to Figure C to establish
a signal search pattern. If the slide is less than 40 meters wide,
the signal search path will be directly up or down the center. If the
victim’s last seen area is well defined, the signal search will follow a
direct path along the fall line (up or down) from this point.
If the slide is wider than 40 meters and there is no last seen point,
cover the entire slide area by using switchbacks in the search pattern
(Figure C). If multiple rescuers are available, establish a search
pattern where the space between searchers is no more than 40
meters and the distance to the edges is no more than 20 meters.
