Updates to Existing Coverage Area

Changes to the Otay Mountains Wilderness and Marron Valley area plan have been deferred until 2014. I've done extensive "field research" in the area and discovered some trails that have been unofficially closed in the interim. The map for this area are current and will be updated when the plan for area is officially changed.

Increased map coverage of BLM lands and publicly accessible dirt roads south of highway 94 to the border.

Added hiking and horseback trails to the Beauty Mountains Wilderness area.

Lowrance Version

Coverage area is now identical to Garmin version.

Topo version is not available due to technical constraints related to the size of the map.

Some of the detail included with the Garmin map is not included with the Lowrance map due to hardware limitations. This is mostly limited to custom graphics and points of interest such as gas stations, ATMs or restaurants that are searchable with the Garmin version.
