When Potter Marsh freezes this year, where will you step onto it? Until this summer, the south end of the marsh gave no good answer. The Alaska Department of Fish and Game says visitors there often parked on the narrow shoulders of the highway to watch wildlife or to reach the frozen ponds.
That changed on August 29, 2026. ADF&G and Alaska State Parks opened a new 200-foot wildlife viewing boardwalk at the south end, along with a viewing platform and an ADA-accessible ice-skating ramp and stairs. The boardwalk stays open year-round. The ramp opens seasonally. The marsh now has a proper winter entrance. What it doesn't have is anyone officially measuring the ice that entrance leads onto.
The South End Used to Mean the Shoulder
The new structures sit near Little Survival Creek, close to where the Old Seward Highway meets Potter Valley Road. That's the south end of the marsh inside the Anchorage Coastal Wildlife Refuge. Interpretive signs along the walkway cover marsh hydrology and the ecosystem. ADF&G calls Potter Marsh Anchorage's most popular wildlife viewing spot, with more than 150,000 visits a year.
The parking came before the boardwalk. Steve Matsuoka, lands and refuges program coordinator for ADF&G, told the Anchorage Daily News that the improved lot created the opening for the project:
"The realization was there's no real good public access to actually view wildlife in Potter's Marsh, even though this parking lot is on the south end of the marsh."
That lot was a separate project. Work started in 2023 with Department of Transportation and Federal Highway Administration money. At the time, KTUU reported plans for 35 spaces. ADF&G's plans also listed a bus stop, a vault toilet and an educational kiosk. Funding for the 2026 boardwalk and ramp came from a Municipality of Anchorage grant through the 2022 American Rescue Plan Act, plus a contribution from ConocoPhillips. Partners included the Alaska Department of Transportation and Public Facilities and the Rabbit Creek Community Council.
A crew of three to six people from Pro Built, the general contractor, worked on it all summer. Owner Luke Homola finished the trim work on August 26. Andrew Huang, the State Parks project engineer, was carrying waterfowl silhouettes out to the new boardwalk to install. ADN described one of the two new boardwalks as a ramp for winter recreation such as ice skating.
Two Entrances, Two Different Jobs
The familiar Potter Marsh is the main boardwalk at milepost 117 of the Seward Highway, at East 154th Avenue. It has about half a mile of elevated, accessible boardwalk with free spotting scopes and educational panels. The south end now does a different job.
| Main boardwalk | New south boardwalk and ramp | |
|---|---|---|
| Location | Seward Highway milepost 117 at East 154th Avenue | Near Little Survival Creek, Old Seward Highway at Potter Valley Road |
| Length | About half a mile of elevated boardwalk | 200-foot viewing boardwalk plus platform |
| Built for | Summer viewing of waterfowl, salmon and wildlife | Year-round viewing, plus winter ice access |
| Winter role | Viewing | Ramp and stairs down to the ice, open seasonally |
| Opened | Long-standing | August 29, 2026 |
Some rules cover the whole marsh. ADF&G does not allow dogs on the Potter Marsh boardwalks, and feeding wildlife is prohibited anywhere in the refuge. If you walk the dog in Rabbit Creek or Potter Valley, the new south lot doesn't change that.
October Is the Gap Between Seasons
The new walkway opened right as the marsh's best-known summer show was ending. ADF&G's fish-viewing guide lists king and coho salmon viewing at Potter Marsh from July through September. The department's Potter Marsh page gives an even earlier window, May through August, for spawning salmon in Rabbit Creek under the main boardwalk. By October, neither calendar points you to the creek.
The birds are the October reason to go. ADN has reported swan pairs stopping at Potter Marsh each October, including gray juveniles, with ducks feeding near them. That's a seasonal pattern, not a promise for any particular day. Audubon Alaska also says Anchorage's fall bird season can run into late fall for gulls and swans.
That note comes from the Anchorage Birding Trail, which Audubon Alaska launched in May 2026 with the Anchorage Audubon Society as a partner. The virtual trail covers 35 sites from Whittier to Westchester Lagoon and east into the Chugach. Each site lists access, parking and restroom details. Alaska Public Media named Potter Marsh as one of the trail's highlighted spots along the Seward Highway. Until this summer, the south end was a site you mostly saw from the highway shoulder. Now it's a 200-foot walk with a platform at the end.
The marsh changes as October goes on. The viewing platform faces open water and lingering waterfowl first. Later in the season, it overlooks the frozen surface the ramp was built to reach.
A Ramp Is an Entrance, Not an Ice Report
People have skated Potter Marsh for years. ADF&G says many skaters use its wide frozen surfaces, and it lists cross-country skiing, fat-tire biking and kite skiing among the refuge's winter activities. ADN's 2018 guide to outdoor skating in Anchorage ran a photo of skaters on the marsh on November 27 of that year. The same guide noted that Potter Marsh is not a rink the Municipality maintains.
That distinction matters more now. Every winter, the Municipality's parks department drills and records ice thickness on a list of lakes, starting around November. The municipal ice and trail status page is where residents are pointed for those readings. Potter Marsh isn't on it. When the south ramp opens for the season, nobody will be posting an official thickness for the ice it leads to.
The marsh itself makes the ice uneven. ADF&G warns that thin ice is common where springs come up in the wetlands. The new boardwalk's own signs are about marsh hydrology, the same water movement that keeps some spots soft.
Skaters have gone out too early before. In the last week of October 2023, KTUU reported people skating at Potter Marsh while open water was still visible. Anchorage Parks Director Mike Braniff called conditions very early-season and dangerously thin. Anchorage's first real cold snaps can come in October or November. None of that reporting gives a reliable freeze-up date for the marsh. A paved lot and an ADA-accessible ramp will make that first cold week easier to act on. They don't change the ice.
Before you step off the ramp
In November 2025, Alaska State Troopers spokesperson Austin McDaniel gave KTUU guidance that fits a marsh nobody else measures:
- Look for at least four inches of ice before standing activities like skating.
- Measure in the spot where you plan to skate, not just at the bottom of the ramp.
- Never assume any ice is completely safe.
At Potter Marsh, add ADF&G's spring warning to that list. Ice that measures well near the ramp may be thinner farther out, wherever groundwater comes up into the wetland.
