3D Mapping of the Seco Creek Sinkhole,
A View of an Edwards Aquifer Recharge Feature from the Inside


By Benjamin von Cramon
and
Geary M. Schindel, P.G.
At

Edwards Aquifer Authority
Training Room
900 E Quincy Street, San Antonio, TX 78215


Mr. Benjamin von Cramon and Mr. Geary Schindel will make a presentation on "3D 
mapping of the Seco Creek Sinkhole, A View of an Edwards Aquifer Recharge 
Feature from the Inside." The presentation will occur on Friday, June 16, 2017 
from 11:30 AM in the Training Room at the Edwards Aquifer Authority, 900 E. 
Quincy Street, San Antonio, Texas. These are informal presentations so please 
feel free to bring your lunch. You may also contact the EAA at 210.222.2204 or 
www.edwardsaquifer.org<http://www.edwardsaquifer.org/> for additional 
directions.

If you are traveling a long distance for the talk, I would recommend that you 
call our receptionist at 210.222.2204 that morning to make sure that the talk 
is still scheduled.  On very rare occasions, we have had to cancel or move the 
talk.  I apologize for any inconvenience this may cause.

Abstract
We will present the results of a pilot program to test the feasibility of using 
3D photoreal mapping of the Seco Creek Sinkhole located in Medina County, 
Texas. This presentation will introduce the audience to 3D film and photo 
techniques utilizing cutting edge technology. The 3D model has multiple uses 
including an educational model of recharge features, cave geology and 
hydrology, and also allows tracking and measurement of sediment transport. The 
Seco Creek (Valdina Farm) Sinkhole is an important recharge site in the Edwards 
Aquifer. The cave is composed of a 150-foot-deep natural shaft that leads to 
approximately 1,000 feet of cave. During heavy rains, the cave shaft will fill 
to the top with rushing water.

The 3D photoreal model offers the opportunity to view the Seco Creek Sinkhole 
without getting dirty or exposed to the vertical drops. It allows for detailed 
analysis of the cave and model can be easily operated with a game controller.

Biography
Benjamin von Cramon, film maker - His body of work defies clean titles and easy 
categories. In 25 years of writing, shooting, and editing for broadcast, 
institutional, and private industry, von Cramon recalibrates between wildly 
disparate projects, from documentaries filmed in prisons to stories in Fourth 
World homesteads to intensely visceral adventure docs deep underground. The 
auteur is as comfortable developing content around issues of great social 
import as he is problem-solving advanced technologies used to innovate the art 
of story-telling.

A Fellow of the National Speleological Society and The Explorers Club, a 
qualified stereo rig tech for Element Technica, and a developer for Autodesk 
Labs, Reality Capture Group, the arc of his dynamic career reflects a sustained 
effort to elevate the latest technologies in their usefulness to education for 
highly visual learning experiences. Each of von Cramon's projects are informed 
by broad humanities education, grounded in highly physical experiences, and are 
inspired by unbound curiosity and tempered hope for the human condition.

Geary Schindel is the Chief Technical Officer of the Edwards Aquifer Authority. 
He has been a caver for more than 40 years and is the President Elect of the 
National Speleological Society (NSS). Geary is a fellow of the NSS and the 
Geological Society of America. He holds a BS degree from West Virginia 
University and an MS from Western Kentucky University.
Thank you.

Geary
