Ray,
Thanks for taking on the task of fixing the tribal boundaries. From personal experience of having done a number of these, it's hard work and easy to make errors. But don't let that discourage you. It feels great once you're complete.

One note - as far as I know, tribal boundaries should just be boundary=aboriginal_lands. Admin levels are designed for areas tagged boundary=administrative. Because tribal lands/reservations have a unique standings they should just be tagged boundary=aboriginal_lands.

Feel free to contact me directly if you need help.

When I was creating the relation, I found the "boundary=aboriginal_lands" thing.

Give a shout if you see anything wrong with this.

And I have not yet, of course, added the bit that will cross into California.

cheers - ray

    Hello -

    I am seeing an interesting editing task at the eastern edge of
    Riverside
    County in California. As of now, I am not expert enough in JOSM to do
    it, but I will, at some point, be able to do it and I will do it
    then.
    Unless someone else wants it.

    I am starting to add lines to define the city boundaries of
    Blythe, CA.
    Almost nothing is there in OSM.

    But the interesting bit is at the nothern part of the eastern edge of
    the city boundary. This line in the Colorado River actually separates
    the states of California and Arizona and is the eastern boarder of
    Blythe but it is also the western border of the Colorado River Indian
    Tribes Reservation (https://www.openstreetmap.org/way/702934460
    <https://www.openstreetmap.org/way/702934460>).

    The issue is that the southern border of the reservation actually
    crosses the CA-AZ state line and this is not seen in OSM. It has a
    "toe"
    sort of shape, facing west. See the eastern edge of the map below.

    https://gis.countyofriverside.us/Html5Viewer/?viewer=MMC_Public
    <https://gis.countyofriverside.us/Html5Viewer/?viewer=MMC_Public>

    So, what I think I need to do is:

    1) Change the reservation from a way into a relation with the proper
    admin level. (Done)

    1a) Fix the southern border of the reservation, which should cover
    the
    road there. The reservation does not include the road in OSM.

    2) Split the way that currently cuts off the toe, but I need to
    not muck
    up the CA-AZ border.

    3) Add the lines for the toe. This also involves moving the northern
    edge of the Palo Verde Ecological Reserve, whose northern edge is too
    far north in OSM.

    4) Actually the nothern edge of the eco reserve needs to be split off
    because it is now also the border of the reservation.

    5) Add the ways created for the norther edge of the toe into the
    reservation's relation.

    And that is it. And I need to not break all of the other things
    around.
    Easy peasy! :--)

    I am open to any suggestions. On the other hand, I am willing to do
    these things when I figure out some of the advanced stuff in JOSM.
    Fun
    stuff.

    cheers - ray
