Provisional Release of Information
Some information available through
Geology has not yet been approved for release by the USGS.
Information not yet approved for release consists primarily of software I
have written to help me do my work. Some of these programs may be
officially published after sufficient field testing has proven their designs,
but others are too small to consider as real publications. Consequently
they are likely to persist in the gray literature.
Please contact me (email
if I can provide additional information or assistance.
