Hike Pins

Tap Drop Pin under the map, or use Pins on the map, where you stand: a cave entrance, the car, a dig, a trail junction. Press and hold the map to drop a pin exactly where you touched; it won't start Go on its own, as there may be a cliff in the way. A pin dropped while a Hike Line records belongs to that line; pins dropped with no line, imported pins and the pins of a deleted line are kept as project pins.

Drop Pin works while a Hike Line records (press and hold it to enter coordinates); Pins on the map works with or without a line recording.

In the pin list, Import brings in GPX waypoints or KML placemarks; Export shares every pin as GPX or KML. Tap Go to head for a pin. If the pin is within 10 m of a line shown on the map and you are within 25 m of that line, the route follows the line, drawn bold. Otherwise a dotted line runs straight to the pin: check the ground before you take it. The chip under the compass stops it.

Press and hold a pin to move it. Open it from the pin list (or Pins on the Details tab) to rename it, add notes, change its color, link a scan, share it as an Apple Maps link or delete it.

Attach photos from the Media tab.

Hike pins anchor to the earth with GPS. Stations anchor to a Cave Line underground using the phone's tracking. Different systems, same project. A station is always on a line; a pin may or may not be.

GPS uses satellites, not cell towers, so pins work in the backcountry. Open sky gives the best fix; trees, canyon walls and cloud cover can reduce it.
