The flour mills lining the river corridor\u00a0get the narrative glory. These stately structures are undeniably impressive. Both\u00a0the Pillsbury A-Mill and the Washburn A-Mill (now Gold Medal Flour), are deservedly two of the\u00a0most\u00a0recognizable Minneapolis landmarks.

These networks are the unsung hero of Minneapolis\u2019 days as the flour capital of the world. Hewed into the soft St. Peter sandstone\u00a0by pick-axe wielding laborers, these tunnels turned St. Anthony Falls into a municipal power plant.<\/p>\n<p>The system relied on three parts. &#8220;Headrace\u201d tunnels diverted water from the river above the falls to the various mills. This water then gushed into\u00a0a series of drop shafts.\u00a0Massive turbines\u2014the ones installed under the Pillsbury A Mill in 1881 were the largest in the world\u2014were placed in these shafts to harness the power of the falling water. Finally, the spent water flowed back to the river below the falls through a \u201ctailrace\u201d tunnel.<\/p>\n<div id=\"attachment_2456\" style=\"width: 410px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/mvt.rpw.mybluehost.me\/.website_3d6664ec\/wp-content\/uploads\/2016\/01\/Headrace_Image.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-2456\" class=\"wp-image-2456\" src=\"http:\/\/mvt.rpw.mybluehost.me\/.website_3d6664ec\/wp-content\/uploads\/2016\/01\/Headrace_Image-300x202.png\" alt=\"One of the headrace tunnels in St. Anthony.\" width=\"400\" height=\"270\" srcset=\"https:\/\/mvt.rpw.mybluehost.me\/.website_3d6664ec\/wp-content\/uploads\/2016\/01\/Headrace_Image-300x202.png 300w, https:\/\/mvt.rpw.mybluehost.me\/.website_3d6664ec\/wp-content\/uploads\/2016\/01\/Headrace_Image-768x518.png 768w, https:\/\/mvt.rpw.mybluehost.me\/.website_3d6664ec\/wp-content\/uploads\/2016\/01\/Headrace_Image.png 850w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/a><p id=\"caption-attachment-2456\" class=\"wp-caption-text\">One of the headrace tunnels underneath St. Anthony Main<\/p><\/div>\n<p><a href=\"http:\/\/arcg.is\/1PhXQZ3\" target=\"_blank\" rel=\"noopener\">This app <\/a>attempts to\u00a0illuminate the importance of these underground networks.
