Great site here! I'm about to purchase an Oregon 450t but was possibly going to try and load some 24k maps of select western states (OR, WA, CA, etc) from this site. I actually have not seen scale mentioned on the pages for most of these maps, so I'm wondering how reasonable it is to derive approx scale from contour intervals.
For instance, on many of the Garmin Compatible maps I've seen on this site, they had between a 20' - 40' contour interval and say "equivalent or better than 24k" in parentheses. So does this mean that most or all maps with say a 20' contour interval are going to be 24k (7.5 quad) detail, as opposed to 100k?
I'm specifically looking at the North West United States map by John H. It doesn't mention a scale, but the contour intervals are 20'.
