Point your iPhone at the mountains and see every summit's name, distance, and elevation, right on the camera view. SummitPeek knows more than 87,000 peaks across the United States and Canada, and labels the ones that actually stand out on your skyline. It uses GPS, not cell service, so it works at the trailhead, on the summit, or anywhere you're out of coverage. • Tap a label for the peak's altitude, distance, bearing, and a map of it • Take a photo with the peak names on it and share it • Label only the peaks above an elevation, or within a distance you choose • If labels sit beside their peaks, drag one onto its peak and the rest follow • Miles and feet, or kilometers and meters SummitPeek works on iPhone and on iPads with cellular, which have the GPS it needs. Peak data comes from USGS, Natural Resources Canada, and Copernicus elevation data.

Read full description

The ACS Technical Manual provides comprehensive response information in a uniform, user-friendly format accessible to both operations planning staff and regulatory agency C-Plan reviewers. This information is designed to be the basic building blocks upon which member company planners develop facility-specific C-Plans. Each tactic is numbered with a key letter to identify the subject: e.g., Tactic S-1 (Site Entry Procedures) is the first tactic in the Safety section, while C-1 (containment Using Snow Berm) is the first in the containment section. These numbers are useful for referencing in member-company response plans.
