Our GPS route of MTB on Tiger Mt. Logging roads. Image is created by Sporttracks.
Start is at almost Tiger summit on 18th SR, then logging roads up to Poo Poo point. You can see two places when "from" road is not the same as "to" road - first one is a little trail from Northern glider launching pad to Southern. The second one is a trail off the main road with lots of rolling stones on it followed by another logging road that joins the main one.
The smaller logging road is the one where Murray slipped on some mud.
Garmin 305 thinks the altitude gain is ~5000 feet for this route, which is obviously too much.
Topo! of National Geographic thinks and gets 3400 feet. However, Miles Ohlrich used an altimeter for this purpose and had some 2600, if I recall correctly, but that one was straight to and from Poo Poo point. The one I have is not symmetric - I did some back to car and then back to company loop close to end, so there are the two spikes twice which should not be at the end of the profile.
