Base Layer Alignment

It seems several base layers do not have the same alignment points in caltopo. As you can see in the two attached files, my trail crosses the stream correctly in the topo base layer but not the other. How can I align my trail with the other base layers? I can not find a simple way to make this alignment accurate.

    Hi Jimmie,

    Not all maps are created equal, nor geo-referenced equally, nor updated with the same frequency. Small variations between layers are expected. That is one of the reasons that we provide so many layers for comparison.
    For more details, please read our recent article on map accuracy.

    Best,
    Julie
