The discovery was made thanks to a graduate student named Alan Hildebrand that notified Alvarez of the evidence of a crater on the Yucatan peninsula, which had never been published in the scientific literature by the Mexican petroleum geologists that had found it. The age of the crater needed to be determined if it was going to be a candidate for the KT boundary impact, but access to the region was limited by the crater being buried over time and the core samples
Haughton impact crater at crater sites on a cold, wet Mars. The Mars Institute and the SETI Institute operate the Haughton–Mars Project at this site, designed to test many of the challenges of life and work on Mars. The non-profit Mars Society also operates the Flashline Mars Arctic Research Station (FMARS) at this site and conducts similar research. Haughton impact crater Haughton impact crater is located on Devon Island, Nunavut in far northern Canada. It is about in diameter and formed about 39 million years ago during the late Eocene. The impacting object is estimated to have been approximately in diameter. Devon Island
