The 2004 Prospection Workshop, "Current Archeological Prospection Advances for Non-Destructive Investigations in the 21st Century," took place May 17-21 at Spiro, Oklahoma.

This year's workshop saw innovations in equipment and application (prepared both in advance and on-the-fly), and a great level of participation by instructors and students alike. Thanks to Spiro Mounds Archaeological State Park for co-hosting this event; resources there made great subject matter for demonstration and data generation. Steve De Vore and a still unknown contributor provided the images below, highlighting some of the people, technology and innovations of the week.
