Talk:Shaanxi tiankeng cluster

Northernmost?
It would seem that "It is the northernmost such landform in the world" needs qualification as there are many karst features in North America and elsewhere (see here for example). I see that line is essentially a direct quote from the China.org.cn reference - perhaps erroneous hype? Vsmith (talk) 15:28, 25 November 2016 (UTC) Zhang Yuanhai, a senior engineer with Institute of Karst Geology under Chinese Academy of Geological Science, said that the scientific value of Hanzhong sinkholes was unmatched.
 * It may be the news service paraphrasing incorrectly. Another article (I just added it to external links, because it has some photos) says this:

"The sinkholes found before are located between north latitude 24 degrees and 31 degrees, but Hanzhong sinkholes are located near north latitude 33 degrees, and the first geological landscape found in the most north boundary of the humid tropical and subtropical Karst landform area, which has exceeded expectations of all geologists," Zhang said.
 * So they might mean China karst, not worldwide. — Gorthian (talk) 19:28, 25 November 2016 (UTC)


 * OK - modified per the Ma Lie ref. Vsmith (talk) 21:15, 25 November 2016 (UTC)
