"1. Sediment spread over a flat plain;
2. Some means of keeping the sediment wet, such as irrigation, rain, or recent watery deposition;
3. People or animals to walk across the soft sediment;
4. A means for the soft sediment to harden soon after receiving the tracks;
5. A sudden flood with a specific flow rate-not so fast that it would erode the ground and destroy the tracks, but fast enough to cap and preserve the tracks." They then comment that a shoreline scenario does not appear to fit the observations, but rather an ebbing and flowing across the broad plains before significant mountain building had occurred. (Jgl note:This would be more consistent with an episode of massive flooding like the Noah Flood.Also tracks made in mud, not covered, and allowed to dry completely often crack through the center of the track. Most Fossil tracks are not cracked-though the strata that they are in may be.)
