This is a list of my hikes I have some information about, minus some which I haven't recorded for various reasons. Often those are because they are repeats. More of these should be excluded from this page for that reason.
GPS statistics, elevation profile and map data are always provided - click on the title of the hike (or "Untitled"). There may be other links for some hikes.
The "Untitled" hikes contain raw data. This means:
The "sep" number present on some hikes is the straight line distance between the start and end of the hike, if significant. If it is not highlighted, it means the hike did not start and end at the same place. Otherwise, it indicates an error, usually because I didn't start the track measurement immediately. I sometimes fix those if the start and end are on the same trail by copying from the end, reversing it, and sticking on the start.
The two numbers listed under gain are the highest point - lowest point and the total gain with reaccumulation. Sorting is done via the latter. My post processing has filtered out insignificant bumps in the elevation data for a more honest reading.
Elevation profiles - I have the capability to apply corrections to my altitude based on known altitudes enroute, but I'm not usually doing it. If the hike is a loop, it generally HAS been corrected to make the starting elevation equal the end elevation, and the intermediate points adjusted accordingly. I also have the capability to set the starting elevation for the hike, and adjust the whole thing. I usually haven't done that either, and I'm not in the habit of calibrating barometric altimeters. Bottom line - the elevation profile SHAPE and elevation changes will generally be quite accurate, but the absolute elevations may be off if I haven't corrected the starting elevation.
Track accuracy - hikes prior to about mid-2013 were collected using an old (pre SIRFSTAR III) unit, which had a tendency to lose connections under heavy cover and no barometric altimeter. Around that time I started using a Garmin Oregon 550, which had a barometric altimeter, and the newer, more sensitive GPS chip which seldom lost connection. When it was retired, I started using a smaller unit as a tracker, and looked at maps on my phone. I don't like using the phone to collect track data because it really runs the battery down. The first of those simpler trackers still had a barometric altimeter. It has recently been replaced with a small handheld Garmin eTrex 10, which is nicer to use, but, unfortunately has no barometric altimeter. Starting November 2023, the tracks are GPS altitudes. I'm smoothing that altitude data to keep it from registering a lot of bogus jumps.
