Just west of Rocheport, the Katy Trail passes a fascinating relic of railroad history: a stone-faced bunker built into the limestone bluffs. Constructed in the early 1900s, this structure served as a secure storage site for explosives used during the Missouri-Kansas-Texas Railroad's operations. Though now on private property, trail users can glimpse its sturdy facade from the path. This hidden feature offers a tangible connection to the region's industrial past, nestled within the scenic beauty of the Missouri River bluffs.
