A close-up of the water ponds at the bottom of Halema‘uma‘u, using a zoom lens on the thermal camera. The smaller hot patches above the main pond show areas of warm water in the smaller ponds.

Staff from the USGS Great Lakes Science Center gaze at the Mackinac Bridge rising above the mist in the Straits of Mackinac, Michigan. The lines they are holding are attached to grappling hooks being used to retrieve acoustic telemetry equipment anchored on the bottom of the straits.

A group of cliff swallow nests made from mud in the river in Swallow Canyon. Many of the nests have birds in them and can be identified by their yellow beaks sticking out.

The water level continues to slowly rise at the bottom of Halema‘uma‘u, resulting in enlargement and merging of the small ponds. Today, the second and third ponds (top of image) observed over the weekend have merged, and are nearly connected to the main pond (bottom of image). For scale, the main pond is about 15 meters (yards) wide.

View looking downstream at the red sandstone walls of Swallow Canyon. This small canyon is one of two canyons that divide Browns Park into series of intermittent alluvial-meandering and bedrock canyon segments. Unlike Red Canyon and Lodore Canyon, the slope of Swallow Canyon is not controlled by debris flows, and thus does not have any rapids.

View looking at a shallow side channel of the Green River in Brown's Park, Colorado. The picture is taken looking downstream from the left bank of the river. In the foreground and on the opposite bank are stands of sandbar willow (Salix exigua). Further beyond, are stands of Fremont cottonwood (Populus fremontii).

Two of the SCREE rafts heading downstream through Swallow Canyon

View looking upstream from a raft on the Green River at the downstream end of Swinging Bridge Canyon, near Flynn Bottom. The eastern end of the Unita Mountains lie in the background. A pump station supplying water to the flooded wetlands of Brown's Park National Wildlife Refuge can be seen on the right near the edge of water.

Andrena spp. seemingly getting a piggyback ride from a bumblebee (Bombus spp.). Researcher was holding the flower on private land in Macon County.

Fruits of Her Labor: the flower on the left has been pollinated and the fruit is developing, but the flower on the right is still being pollinated, highlighting the importance of bees to humanity's food resources. 

The center of the composite flower looks like a "landing zone" and has evolved to guide pollinators to its nectar/pollen.

The photo shows the SCREE Powell 150 expdition camp at Big Pine Campground in Red Canyon of the Green River, Utah. The large green tarp was set up to keep the kitchen area and campers dry. Two very large ponderosa pines are in the center of camp, and surely were witness to the 1869 Powell expedition.
