Here is a second go at the image, I thought this version might seem a bit simpler. Basically, Google Earth ruler says from where I suggested they might park, all the way south to Howland Hill Rd. straight up, is 2.8 miles. And from the campground at west, to the edge of Crescent City, California is about 3.5 to 4 miles.
Go to this MAP here, and enlarge to about 200%. http://www.nps.gov/carto/PDF/REDWmap1.pdf
It will show details of Hy. 199. Now, the map has north upward, and my image below has north toward the bottom. Both the map, and my diagram, show the pre-existing hiking trails. The Grove of Titans has to be between those, almost certainly. The pink area is where I would begin to look.
You could find a TOPOGRAPHY MAP at topozone.com, but REMEMBER, the article said that the topography maps WERE WRONG. The only reason I'd even use the topography map, is to try and find the "WARREN" of small valleys around a peak on the map, even though the map is wrong, because they still headed for what they thought that feature was.
Google Earth's satellite imagery is probably going to be better than a topo map for accuracy. Be sure to tilt the horizon to see the hills and valleys better. I also grab the rotator and spin it around to look at it from every angle. That's how I figured out the hill of Blue Ledge Mine in our area.
If I find the trees, I won't disclose the exact nature of where they are. The illustrations here show no more than what an existing article already somewhat implies. If I do find them, I will share photos and video though. My plan, hopefully, is to go next week.
