Small negative gravity anomalies are found in gravity data from along the northwestern shoreline of the Yucatan Peninsula. These anomalies are shown to be due to elongate, shallow anomalous porosity zones in the Tertiary carbonates. These zones are caused primarily by groundwater solution and are presently active conduits for groundwater flow.

- Analysis of geomorphic, soil, and topographic data in the northern Yucatan Peninsula confirms that the Chicxulub impact crater affects the area's surface features, with evidence of distinct sedimentation patterns influenced by the impact.
- The crater features a prominent 83-km-radius moat with sinkholes and is surrounded by stepped topography, including outer and inner troughs marking buried ring faults.
- The findings support that the impact basin's main diameter is about 180 km, though evidence suggests the eroded rim could extend up to 260 km.
