your killing me Jeff. here's my process: (1) I am going to start searching timeline, dates, routes of travel for the Loftus brothers to and from Goldrun and pinpoint on a map.
(2) The "Oregon Wagon Road" ran through that area. Gotta find its path from nearest railroad terminus at the time (Likely, CA).
(3) Plot potential routes of travel from the (a) wagon road to the (b) railroad terminus.
(4) Plot ghost towns, mine camps, ranches, military roads/outposts in area.
(5) Plot shortest routes, days of travel based on terrain, river/stream crossings
Identify 3 possible routes and then, and only then, start looking for 2 lakes and the bald hills.
I've been in that country. The lakes very well could have changed. Army Corpes of Engineers very active in southern/eastern Oregon after WW2
with water projects. Those damn bald hills are everywhere in that part of the country so that's the last clue I will look for.
Anybody out there want to weigh in please do. There are no bad ideas at this early stage of researching a treasure lead.
