Upper Logan River/Hansen Hollow, 9 February, 2025

The original plan was to go up Smithfield Canyon, but a scouting trip the day before found the route was a sheet of ice with gravel patches, and a morning grooming report indicated that the trail had likely become treacherous, with a layer of new snow over slick ice.  Instead we opted to go to the Franklin Basin Winter Trailhead and follow the upper Logan River. Just as we were turning into Franklin Basin Road, a sheriff deputy said there was search and rescue in progress and the parking area was closed.  We stopped at the first turnoff to consider our choices and decided to go to Sink Hollow.  The lead car took off, but before the other two left a deputy came up to say that the area was now open.  Fortunately the lead car had a walkie-talkie on and was told what the officer said, so we decided to return to the Franklin Basin Winter Trailhead, as previously planned.

The search and rescue was for a teenager who got separated from a group the day before:
The search began Saturday afternoon when the boy was reported missing. He had been riding a snowmobile with a group near Franklin Basin Road about 2½ miles southwest of Gibson Basin in Franklin County, Idaho…the teen was eventually located in a forest area southwest of where he was last seen on Saturday, having spent the night in below-zero temperatures. Temperatures dropped to minus 15 degrees Fahrenheit in the area”. https://www.ksl.com/article/51249130/missing-12-year-old-snowmobiler-found-near-utah-idaho-border
Our outing was less stressful, fortunately.  Ten hikers were in the group: Brent L., Susan, Kathy, Jane E, Chris, and Linda were on snowshoes; and Dave P (leader), Catherine, Teresa, and Dave W were on skis. The weather was beautiful with mostly sunny sky, calm wind, and an inch or two of new snow on a firm base.  We enjoyed seeing the Logan River and several beaver dams as we made our way along the west bank. There were animal tracks all over, the straight-line ones were probably coyote and the wandering ones fox, but they were not fresh enough to be certain.  When the river route was too gullied and brushy we rejoined the road for about a half mile and then turned back to the river above Beaver Spring for lunch. We admired the Logan River Observatory's climate monitoring equipment, and Dave W checked out their nearby aquatic monitoring station at the river.  We looked for a log to sit on for lunch without success and ended up near the river across from Hansen Hollow, standing or using whatever we had to sit on the snow.  Kathy and Catherine treated us with cookies.  On the way back we saw a dipper in Beaver Spring pond and a kingfisher.
