The lyrics by A. O. McGrew.

Verse 1
Way out upon the Platte, near Pike's Peak we were told,
There by a little digging, we could get a pile of gold,
So we bundled up our duds, resolved at least to try
And tempt old Madame Fortune, toot hog, or die.

Gold was later mined in the area with modern heavy machinery, but it was not in concentrations that could be obtained by pick and shovel.
"Pike's Peak or Bust" was a "bust."

From Irwin Silber and Earl Robinson, 1967, "Songs of the Great American West," Macmillan Co., NY; Pp. 142-144, with musical score.
