Figure 7 (on map sheet):
Top cross section: all vertical elevations on the elevation scale (on left and right sides of cross section) were shifted down slightly so mean sea level (MSL) starts just below the ground surface (on left side of the cross section). The original that was posted on August 26, 2024, showed MSL equal to the elevation of the ground surface on the left side.

Middle cross section: all vertical elevations on the elevation scale (on left and right sides of cross section) were shifted down slightly so mean sea level (MSL) starts just below the ground surface (on the left side of the cross section). The original that was posted on August 26, 2024, showed MSL equal to the elevation of the ground surface on the left side.

Top, middle, and bottom cross sections: the vertical scales on all 3 cross sections were rescaled for correctness. It was determined that the scales in the source report, Surles (2007), were scaled incorrectly and this mistake was carried over in figure 7 when it was digitized for this publication (SIM 3524). The vertical scales were corrected (both the left and right vertical scales) for each one of the 3 cross sections in figure 7.
