Fig. 4.8. Increasingly smoothed surfaces representing the Formative 2 occupation in the San Agustín-Isnos survey zone. Inverse distance powers used in the smoothing were (from top left to bottom right) 4, 2, 1, .5, .25, and .001.

Fig. 4.13. Increasingly smoothed surfaces representing the Formative 3 occupation in the San Agustín-Isnos survey zone. Inverse distance powers used in the smoothing were (from top left to bottom right) 4, 2, 1, .5, .25, and .001.

Fig. 5.2. Increasingly smoothed surfaces representing the Regional Classic occupation in the San Agustín-Isnos survey zone. Inverse distance powers used in the smoothing were (from top left to bottom right) 4, 2, 1, .5, .25, and .001.
