What to look for in nature in Utah this October

When do the leaves change in Utah, and where is the color in October?

• Bigtooth maple in the Wasatch canyons

  Late September into early October; lower canyons last · Logan Canyon, the Alpine Loop, Mount Nebo Loop, Big and Little Cottonwood, Millcreek

  The Forest Service describes bigtooth maple as growing between about 4,200 and 9,200 feet in Utah, most thickly on moist, north-facing slopes; that is why one side of a canyon can be scarlet while the facing side stays olive. By October the winged seeds have mostly dropped, between mid-August and early October. The Uinta-Wasatch-Cache National Forest points drivers to the Logan Canyon Scenic Byway, the Mirror Lake Highway and the Mount Nebo Loop. Go on a weekday morning; the canyon roads fill by noon on weekends.

• Aspens, and Pando

  Early to mid-October on the high plateaus · Guardsman Pass, Bonanza Flat, the Mirror Lake Highway, Fishlake and Dixie national forests

  Aspen stands turn as a single color because each is usually one clone, grown from one root system. The most famous is Pando, about a mile southwest of Fish Lake on State Route 25: the Fishlake National Forest describes it as a single aspen spreading over 106 acres, with more than 40,000 stems and a weight of nearly 13 million pounds. Trails start near Doctor Creek Campground. On the Dixie National Forest, near Bryce Canyon and Cedar Breaks, aspens mix with maples and oakbrush.

• Cottonwoods in the red-rock canyons

  End of October into early November · Zion Canyon, the Virgin River, the Colorado and Green river corridors

  The National Park Service says Zion’s color starts at the highest elevations and works down to Zion Canyon at the end of October and in early November. The Fremont cottonwoods along the Virgin River are the last big yellow of the year in Utah,. Moab’s river bottoms follow a similar schedule.

What is happening on the Great Salt Lake in October?

• Eared grebes by the million

  Fall staging through October; departure in November or December · Open water across the lake; rafts can often be seen from Antelope Island

  The DWR’s Great Salt Lake Ecosystem Program counts as many as 5 million eared grebes in fall, at times half to 90 percent of the North American population. They eat almost nothing but brine shrimp while they are here. As they fatten, their flight muscles shrink and their digestive organs grow until the birds cannot fly; then, beginning in November or December, they rebuild their muscles and leave in huge flocks over three to four weeks for a nonstop flight to the Gulf of California.

• Ducks, geese and the first swans at Bear River

  Ducks building all month; tundra swans from late October · Bear River Migratory Bird Refuge auto tour route, west of Brigham City

  The refuge’s month-by-month guide says most shorebirds have gone by October, leaving avocets, marbled godwits, greater yellowlegs and long-billed dowitchers, while the duck count nears 200,000. Canvasbacks, goldeneyes and lesser scaup arrive late in the month, and cinnamon teal leave. The DWR’s swan survey history says most tundra swans reach Utah around the first of November, and peak fall numbers of 40,000 to 60,000 are regular, mostly on the refuge and nearby marshes; the refuge puts the swan peak in the week before Thanksgiving. The DWR says statewide duck numbers often peak in mid-September, while the refuge’s own count tops out in early November; either way the auto tour route, open daily in daylight, will be busy.

• The Antelope Island bison roundup

  Roundup Saturday, October 24; working days October 27–29 · Antelope Island State Park; public viewing at White Rock Bay

  Utah State Parks keeps the island’s herd at about 500 to 550 animals. With 100 to 200 calves a year and no predator able to take an adult, the herd must be thinned. On October 24 riders assemble at 9 a.m. and push the bison toward the corrals, usually finishing between noon and 3 p.m.; spectators do not register and gather at the White Rock Bay viewing area. From October 27 to 29 the animals get health checks and are sorted, with free public tours; surplus animals go to an online auction in early November (the park page lists both November 3 and 4). Bring binoculars and stay well back from any bison, penned or not.

Which birds are migrating through Utah in October?

• Sandhill cranes in the Uinta Basin

  Arriving now; guided viewing Saturday, October 10 · Fields near the Green River at Jensen; Pelican Lake and Ouray National Wildlife Refuge

  DWR’s Northeastern Region says the cranes are easy to find in the basin’s fields during migration and have already begun to arrive. They stand about 4 feet tall, wear a crimson crown on a gray body, and call loudly enough to be heard up to 2.5 miles away. The division runs two free auto tours on October 10: 7 to 9 a.m. from Jensen Nature Park, 8775 E. 6000 South, and 5 to 7 p.m. from the commuter lot at Highway 40 and State Route 88, where the evening group watches cranes come in to roost near Pelican Lake and the Ouray refuge. Register in advance on Eventbrite; scopes are provided, but bring binoculars if you have them.

• Hawks along the Wasatch

  Late September through October · Ridgelines above the Wasatch Front; Goshute Mountains just over the Nevada line

  HawkWatch International, based in Salt Lake City, opened an exploratory count site in the Wasatch Mountains this fall when wildfires shut two of its regular sites, and its crew tallied more than 600 migrating raptors in the first three days. The group has not published public-visit details for the new site. Its long-running Goshute Mountains station in Nevada, south of West Wendover, can be reached by visitors willing to hike about 2.5 miles with 1,800 feet of climbing.

• Juncos, sparrows and the winter crowd

  All month, building by Halloween · Canyon mouths, riparian thickets, backyard feeders

  Dark-eyed juncos come down from the mountains and in from the north, white-crowned sparrows fill the brushy edges, and northern harriers return in numbers to the marshes. Tally them on October 10, the worldwide October Big Day, or on any walk; a list from your own block counts as much as one from a famous refuge.

Where can you still see red kokanee salmon in Utah in October?

• Electric Lake

  First half of October · Wasatch Plateau, Emery County

  The DWR lists the first half of October as the viewing window at Electric Lake, one of the later runs in the state.

• Smith and Morehouse Reservoir

  Late September to mid-October · Weber River drainage, east of Oakley

  Up the Weber River road from Oakley at the edge of the western Uintas, with red fish in the inlet stream into the middle of the month.

• Fish Lake, self-guided

  Through October · Twin Creeks boardwalk, Fish Lake

  This year’s Fish Lake viewing event was canceled because too few fish came in to spawn, but the DWR says the Twin Creeks boardwalk is still open for looking on your own. Combine it with a walk in Pando down the road.

What can you see in Utah’s night sky in October?

• Jupiter and the crescent moon rise together

  Tuesday, October 6, from about 3 a.m. · Low in the east-northeast

  States farther east watch the moon cover Jupiter on this date. In Utah the moon is still below the horizon when Jupiter slips behind it, and the International Occultation Timing Association (IOTA) lists the planet coming back out from the moon’s dark edge at about 3:09 a.m. in Salt Lake City and Ogden, when the moon is only 1 degree up, a few minutes after moonrise at 3:02. With the Wasatch to the east, almost nobody will see that moment. What everyone can see is the thin crescent and bright Jupiter climbing the eastern sky side by side until dawn; in southern Utah, where the moon rises later, Jupiter is already clear of the moon when the pair comes up.

• The Hunter’s Moon

  Sunday, October 25 and Monday, October 26 · East at dusk

  Full moon falls at 10:12 p.m. Mountain time on the 25th, and to the eye it is just as full on the 26th. Salt Lake City sees it come up at 6:01 p.m. on the 25th, 32 minutes ahead of sunset (6:33), and at 6:34 p.m. on the 26th, three minutes after the sun goes down; St. George’s moonrise on the 25th is 6:15 p.m. Ignore any supermoon billing; the moon is nowhere near close enough this time.

• Orionid meteors

  Before dawn, October 21 and 22 · Anywhere dark; look up and east of south

  The Orionids, bits of Halley’s Comet, run from early October into November with a broad peak on October 21–22. The gibbous moon sets at 2:46 a.m. on the 21st and 3:51 a.m. on the 22nd in Salt Lake City (2:58 and 4:01 in St. George), and dawn twilight does not begin until about 7:20, which leaves between roughly three and a half and four and a half hours of darkness. A lawn chair at any state park away from the valley glow is enough.

• Draconid meteors

  Evening of Thursday, October 8 · Look north after dark

  A slow, unpredictable shower best in the early evening, which makes it good for children. With moonrise not until 5:24 a.m., the whole evening is moonless.

• Saturn all night, Jupiter and Mars before dawn

  Saturn at opposition October 4; moon near Saturn October 23–24; Mars at the Beehive October 11 · Saturn in the east at dusk; Jupiter and Mars in the east before sunrise

  Saturn’s opposition date is October 4; it rises at dusk, sets at dawn and shines pale gold without twinkling, with the moon alongside on the 23rd and 24th. Venus is a brief, low glint in the west during October’s opening days and reaches inferior conjunction on the 23rd. Before sunrise the eastern sky belongs to Jupiter, and on the 11th red Mars sits inside the loose Beehive star swarm, a pairing worth pulling out binoculars for.

What is blooming and fruiting in Utah in October?

• Rubber rabbitbrush

  September into October in the valleys and deserts · Roadsides, foothills, disturbed ground statewide

  According to Forest Service research summaries, mountain populations bloom in July while low-desert plants flower much later, which is why the valleys go mustard yellow just as the mountains go gold. On warm afternoons it draws late bees and butterflies, and pronghorn eat both the flower heads and the new leaves in fall.

• Big sagebrush in flower

  Late summer into fall; seeds shed through winter · Valleys, benches and the West Desert

  Sagebrush flowers are tiny and easy to miss, but for many people the pollen is a fall allergy trigger. The Forest Service calls Wyoming big sagebrush perhaps the single most important plant to sage-grouse, and its evergreen leaves feed mule deer and pronghorn through the winter.

• Pinyon cones open

  Late September and October · Pinyon-juniper woodland from Moab to Cedar City and the central valleys

  Pinyon cones need two years to ripen, then spread their scales from late September through October. Heavy crops come only every three to seven years and are cut by drought, so after this year’s heat and drought the harvest may be thin in many places. Pinyon jays, scrub jays, Steller’s jays and Clark’s nutcrackers cache the seeds and forget some, which is how new pinyons get planted. If you want to gather nuts for your own use, check with the local Forest Service or BLM office first.

• Maple keys and Gambel oak acorns

  Maple seeds down by early October; acorns through the fall · Foothills and canyon mouths along the Wasatch

  Birds and small mammals eat bigtooth maple seeds, and elk and mule deer browse the twigs. The DWR says this spring’s early warmth, hard freezes and summer drought damaged the berries and acorns that bears depend on, so expect a poor acorn year on many slopes and hungry animals looking elsewhere.

What are Utah’s bears, elk and deer doing in October?

• Hungry black bears

  All month, until denning · Canyons, campgrounds and foothill neighborhoods

  As of August 25 the DWR had responded to 168 bear incidents this year, twice the 83 of 2025. The division blames a failed natural food crop: a warm spring, hard freezes and then heat and drought damaged the berries, acorns and roots that make up about 90 percent of a black bear’s diet, pushing bears downhill into town. Fall is when bears feed hardest, so bring in bird feeders and pet food, keep trash in the garage until pickup morning, and lock food in your vehicle at camp.

• Elk bugling fades

  Early October · Aspen parks and meadows in the Wasatch, Uintas and high plateaus

  The rut usually peaks in late September, and bulls still bugle at dusk and dawn in the first days of October. The general-season any-bull rifle hunts open October 3, so listen from roads and trailheads rather than wandering into the timber.

• Mule deer on the move, and a disease check

  Through October and November · Foothills, benches and highways between summer and winter range

  Storms in the high country push mule deer down toward the sagebrush, and deer cross roads more often at dawn and dusk. Chronic wasting disease is present across Utah, mostly in the northeast and southeast; the DWR runs check stations October 17–26 during the rifle hunt and says 78 percent of hunters have never had a deer tested.
