This quadruple site (Fig. 1) illustrates typical examples of Kansas cyclothems of Pennsylvanian age.

Site 10: Iola and Wyandotte cyclothems (Figs. 2, 6). I-435 exit at Holliday Road, NE¼NW¼, Sec.6, T.12S., R.24E., Ed-wardsville 7½-minute Quadrangle, Johnson County, Kansas.

The best way to get to this section is to proceed south on I-435 from Kansas 32, cross the Kansas River and take the Holli-day Road exit around to the right, pulling off to park on the shoulder before meeting Holliday Road. The lower part of this section (up to the lower Argentine) is easily accessible on the east side of this ramp road, the upper part is accessible on the west side of this road, but requires more careful climbing.

Site 11: Swope and Dennis cyclothems (Figs. 2, 7). U.S. 69 roadcut by Jingo, SW¼SE¼, Sec.31, T.l8S., R.25E., New Lancaster 7½-minute Quadrangle, Miami County, Kansas.

This section is exposed continuously along the east side of U.S. 69 and the north side of a gravel section-line road that crosses U.S. 69, 13 mi (21 km) south of Kansas 68 (Louisburg) exit and 6 mi (9.6 km) north of Kansas 135 (LaCygne) exit. Park along the section-line road east of U.S. 69.

Site 12: Plattsburg cyclothem (Figs. 2, 8). Kansas 47 Altoona lower roadcut, near NW corner, Sec. 17, T.29S., R.16E., Altoona 7½-minute Quadrangle, Wilson County, Kansas.
