5 February 2023
- 08:1108:11, 5 February 2023 diff hist +8 Chief Mountain Corrected age of Precambrian rocks (Altyn Fm, Belt Supergroup) making up the mountain. Brings the article into better agreement with the related Lewis Overthrust and Belt Supergroup articles.
4 February 2023
- 19:0219:02, 4 February 2023 diff hist +1 Triple Divide Peak (Montana) →Geology: Fixed age of Lewis Thrust, now consistent with main wiki article on topic (and geochronology).
- 18:5718:57, 4 February 2023 diff hist +16 Lewis Overthrust Corrected age of thrust (must be younger than footwall Cretaceous) and age difference of hanging wall (mid-Proterozoic Belt Supergroup) vs. footwall. This intro is now more consistent with the main body of the article.
16 March 2017
- 07:5607:56, 16 March 2017 diff hist +270 Boney Peak Removed description of peak as "sandstone" which is incorrect. The Boney/Sandstone Peak area is mainly volcanic.

22 November 2014
- 23:1423:14, 22 November 2014 diff hist −2 Sawatch Range Extended the latitude range farther south -- the Sawatch is generally considered to continue south of Monarch Pass, including Mt. Ouray. A plausible end is US 285 just E of Saguache, where a S. Saguache Peak ridge disappears under Saguache Creek alluvium.

5 September 2008
- 04:5704:57, 5 September 2008 diff hist +48 m Paleothermometer Fixing some symbols -- seemed to be garbled by transcription.
- 04:4604:46, 5 September 2008 diff hist +120 Paleothermometer Took another pass at the 13C-18O clumping paleothermometer. Seems basically legible now, but still rough.
4 September 2008
- 01:1701:17, 4 September 2008 diff hist +653 Paleothermometer Tried to improve the section on 13C-18O paleothermometry. It's still pretty rough though.

5 April 2008
- 07:2607:26, 5 April 2008 diff hist +1,441 Mass-independent fractionation Added introductory material bearing on the topic's significance. Also added references for ozone. The article is far from complete, however.

24 February 2008
- 05:5505:55, 24 February 2008 diff hist +10 Javelin Corrected description of dating of the Schöningen spears. According to the original reference (Thieme, 1997, Nature v. 385, p. 807-810), the spears are stratigraphically correlated to MIS-11.
13 September 2007
