From 1872 to 1878, MBK took part in George A. Wheeler's Geological Survey titled "Explorations and Surveys West of the One Hundredth Meridian" in "Nevada, Utah, Colorado, New Mexico and Arizona." This was one of four government backed major surveys of the west. Wheeler had parties in the field each summer from 1872 to 1878. Fredrick William Floyd was also on this survey. FWF became a friend of the family and MBK introduced FWF to HMK. About 12 years later FWF and HMK married. (journal of HMK and Internet Research)

*extract*
...On Saturday, May 28, 1892, in Olney's law office in San Francisco, the club's name and purposes were agreed upon, and Olney drew up the Articles of Incorpora-tion. One week later the Articles and Bylaws were signed and the officers of the club were elected. There were 182 charter members.
The first directors were John Muir, President; Warren Olney, Vice-President; William Dellam Armes, Sec-retary; J. H. Senger, David Starr Jordan (president of the new Stanford University), Robert M. Price, Mark Brickell Kerr, Willard D. Johnson, and John C. Branner (later president of Stanford). Muir remained president until his death on December 24, 1914. From the outset both universities, California and Stanford, were repre-sented on the Board, and for many years thereafter much of the strength and initiative of the club came from their faculties and student bodies. Prominent names appear as signers of the Articles: among them William H. Beatty, Chief Justice of the Supreme Court of California; George Perkins, United States Senator; W. L. Jepson, California's outstanding authority on its trees and flowers; and the late Will Denman, formerly a senior judge of the United States Court of Appeals.
