Once a month, beginning Spring Equinox, the Finger Lakes chapter of the American Society of Dowsers sponsors field surveys of sacred sites around Onondaga Lake. One Saturday each month, survey members gather at Onondaga Park and investigate at least two sites. Most will be the third Saturday, except May and June.
