Summary of findings from coastal dynamics monitoring at Gulf Islands National Seashore in Mississippi and Florida from 2018 to 2024. This article presents how the park has changed in terms of dune topography and shoreline position over the past several years for Horn Island, Petit Bois Island, West Petit Bois Island, Fort Pickens, and Perdido Key.

The camp of Peace Chief Black Kettle was located on the floodplain of the Washita River within the Western Red-Bed Plains geomorphic province of the Great Plains. The area is characterized gently rolling hills of nearly flat-lying Permian red sandstone and shale Links to products from Baseline Geologic and Soil Resources Inventories provide access to maps and reports.
Palo Alto Battlefield National Historical Park
Hydrology at Palo Alto Battlefield
- Type: Article
Palo Alto Battlefield is located within the Rio Grande Delta. It is a landscape characterized by low ridges and shortened meanders of former channels of the Rio Grande. These meanders, called resacas, once functioned as part of a vast distributary network during times of flood.

Natural Bridges National Monument contains three of the largest natural bridges in the world. They were carved into the Permian Cedar Mesa Sandstone by stream action in White and Armstrong canyons. The close proximity of these large natural bridges to one another as well as their varying age and geomorphic history are important parts of the monument’s geologic significance.

Great Lakes Network staff assisted Midwest Region staff in a mapping project that reveals a whole new way of looking at the Great Lakes parks.
Gulf Coast Inventory & Monitoring Network
Coastal Dynamics Monitoring at Padre Island National Seashore, Texas: 2017-2023
- Type: Article
Gulf Coast Network Coastal Dynamics report for Padre Island National Seashore. In 2023, a shoreline position survey was completed for the entire length of the park's gulf shore, and a fixed set of 23 topographic transects distributed along the Gulf shore were surveyed for elevations. This report presents results for the 2023 season and compares change over time.

Although groundwater levels remain shallow enough to support mature cottonwood trees, the Fremont River in Capitol Reef National Park may be at risk for progressively lower flows over time—reducing the flooding needed for new cottonwood recruitment. Find out why—and what else the Northern Colorado Plateau Network is learning about the park’s riparian systems—in this article.

"We generally use the term mid century to differentiate the buildings of the post World War II years from the output of the pre-War years. Mid century is an interesting term. It links architecture in the US to the growth and change resulting from post-War power and prosperity, even as the geo politics of the Cold War cast a haze of uncertainty over the period. Like everything else at mid century, architecture was shaped by these conditions." - Mary Reid Brunstrom

Estuaries are buffer zones between river (freshwater) and ocean (saltwater) environments that are affected by tidal oscillations.

Storm surge may severely impact coastal geomorphology and inundate park resources. Brought by coastal storms, storm surge can be dangerous and have lasting effects. Coastal areas that remain at low elevation are prone to the effects of storm surge. The magnitude of a storm surge is increased when coupled with sea level rise.
Glacier Bay National Park & Preserve
The impacts of glacier retreat and landscape change
- Type: Article
Read the summary and link to a published article that shows landscape and socioeconomic impacts of glacier retreat: Loso, M. G., C. F. Larsen, B. S. Tober, M. Christoffersen, M. Fahnestock, J. W. Holt, and M. Truffer. 2021. Quo vadis, Alsek? Climate-driven glacier retreat may change the course of a major river outlet in southern Alaska. Geomorphology

Development and Documentation of Geomorphic Characteristics in Support of a Cultural Resources/Archaeological Favorability Model for Death Valley National Park
- Type: Article
Applying geomorphic principles to help understand human prehistory in the context of desert landscape evolution has been an integral part of archaeological investigations for many decades(Waters, 1992).
Northeast Coastal and Barrier Inventory & Monitoring Network
An aspiring geologist gains a well-grounded skill set from the Geoscientists-in-the-Parks (GIP) internship program
- Type: Article
After graduating with a master's degree in Earth & Ocean Science, Jin-Si Over discovered the Geoscientists-in-the-Parks Program. While interning as a geomorphology assistant for the Northeast Coastal and Barrier Network, she worked and lived on the shores of Gateway National Recreation Area learning a skill set that would further her career goals as a geographer.
Dinosaur National Monument
Predicting Vegetation and Topographic Change in Response to Altered River Flows on the Northern Colorado Plateau
- Type: Article
Lots of things can impact the quality of your raft trip. Weather. Water levels. Packing the right (or wrong) gear. But would you expect plants to play a role? Riparian plants influence the shape and character of rivers—and river flow helps determine what grows where. This model can help river managers predict the downstream effects of shifts in flow, and respond accordingly. The model was tested in Dinosaur National Monument.
Arches National Park
Vital Signs Monitoring at Courthouse Wash, Arches National Park, 2010–2019
- Type: Article
Riparian areas are oases of life. To evaluate the health of riparian systems, the Northern Colorado Plateau Network monitors physical and biological attributes of wadeable streams. Monitoring at Arches National Park from 2010 to 2019 revealed that the Courthouse Wash system is currently driven by natural processes rather than human effects. Future stressors are likely to be climate change and exotic-plant invasions.

Alaska’s parks are dynamic and are undergoing constant geomorphic change as glaciers and streams erode and cliffs collapse. Based on climate projec-tions, some permafrost in Alaska will thaw, and many glaciers will thin and retreat, over the remainder of this century, uncovering potentially unstable valley walls. Both permafrost thaw and glacier thinning will contribute to an increase in the incidence of landslides.
Apostle Islands National Lakeshore
Formation of the Stockton Island Tombolo: A 6,000 Year Process
- Type: Article
A tombolo is a landform that develops over time between two formerly separated islands due to specific conditions. Subsequently, tombolos are quite rare. At Apostle Islands, the largest tombolo extends between the previously separate Stockton and Presque Isle Islands. The location and orientation of these islands, and the direction of prevailing storms and winds, contributed significantly to the tombolo formation.
Natural Bridges National Monument
Wadeable Streams Monitoring at Natural Bridges National Monument, 2010–2018
- Type: Article
Riparian areas are oases of life. To evaluate the health of riparian systems, the Northern Colorado Plateau Network monitors physical and biological attributes of wadeable streams. These indicators tell us about “normal” conditions and give park managers early warning of potential problems. Monitoring at Natural Bridges National Monument from 2010 to 2018 revealed how flood events caused changes in the channel, and how plants have responded.
