A small dark blur upslope materialized into a loping wolverine, coming straight toward us! Afraid this wolverine wanted to share our lunch, we left our backpacks where they lay, and hurried out of its path.High on the west side of Logan Pass in Glacier National Park, bloated marmots grazed and pikas chirped, darting over rocks with mouths full of grass and flowers. My family and I were enjoying lunch, noting our luck in relative seclusion from the crowds often drawn to this popular pass.
