Downloaded maps are a great tool!  But they are only in app - you can not find them or use them on the website.

If you have taken the time to load maps before you left a cell coverage or wifi coverage area (you can not load new maps after you are out of coverage area) you will find them inside your PROFILE in the app (lower right corner) and then by going to the PRO TOOLS tab. You can also find them by clicking on the spyglass at the bottom of the app screen, then clicking on the "folded map" icon in the lower right of the map screen and then opening OFFLINE MAPS tab in the list.
