Once he arrived in what would later become the

Broadway and

[Sargent, Charles Sprague]
Garden and Forest, Volume 7
Garden and Forest Publishing Company, 1894, page 7, , accessed 10 March 2013, Quote: "He rarely went out, except to the store of his publishers under the Astor House; he never went to the theatre, or, indeed, to any place of amusement. He took no recreation of any kind so far as I could learn. He did not appear to visit anywhere, nor did he appear to have any acquaintances. His heart was wholly in his book; it was his joy by day and his dream by night. His stay and life in the city during its incubation was his great trial. He pined for the prairies and the free open air of the wilderness. New York to him was a prison, and his hotel a cage."

Gregg wrote about local people and described Indian culture and artifacts. The book was an immediate success and established Gregg's literary reputation.
It went through several editions, sold a large number in England, and was translated into French and German.
The map he produced of the Santa Fe Trail and surrounding plains was the most detailed up to that time, and his suggestions of where the Red River headwaters might be found inspired the journey of
Randolph B. Marcy and
George B. McClellan in 1852.

He left field notes with his former partner Jesse Sutton and gave Sutton instructions what to do with them if he did not return from what might turn out to be his last trip.
Shortly thereafter he visited placer mines on the
Trinity River.

intending to find "Trinity Bay" by crossing unknown territory and following the line of latitude westward.
The roster of the party was: Gregg; Thomas Seabring of Ottawa, Illinois; David A. Buck of New York; J. B. Truesdale of Oregon; Charles C. Southard of Boston; Isaac Wilson of Missouri; Lewis Keysor Wood of Kentucky; and James Van Duzen.
They had been told by Indians that the Pacific Ocean was an eight-day journey, so they provisioned for ten days' rations.
A few days past the start, David A. Buck discovered the
South Fork Trinity River, where the party encountered a group of Indians who fled from them.
The party took smoked salmon from the Indian rancheria and set up camp only a short distance away.
That evening eighty warriors arrived at the Gregg party camp, but only a discussion followed; the Indians warned them against following the Trinity to the sea, and said to go westward and leave the river,
a trail which later became part of
California State Route 299
State Route 299 (SR 299) is an east–west state highway in the state of California that runs across the northern part of the state. At , it is the third longest California state highway (after Route 1 and Route 99). Route 299 begins at US 101 ...
.
The party instead followed the river until it became impassable, then went west.
By November 13, the provisions were gone and the party began to subsist on deer and smoked game,
averaging a day until they got to the

forests, after which they averaged only about a day.
About six weeks after they started,
they emerged from the redwood forests and saw the ocean at the mouth of a watercourse which they called the
Little River.
After exploring slightly to the north, they turned south along the coast and camped at Trinidad.
Leaving Trinidad, they crossed a large river, but the fed-up members of the exploring party did not wish to wait for Gregg to determine the latitude of the mouth, and so pushed off without him.
When he caught up with the group, his temper flared, and they named the river
Mad River due to the outburst.
On December 20, 1849, David A. Buck was the first to discover what this party named "Trinity Bay", which a few months later became known as
Humboldt Bay
Humboldt Bay is a natural bay and a multi-basin, bar-built coastal lagoon located on the rugged North Coast of California, entirely within Humboldt County, United States. It is the largest protected body of water on the West Coast between Sa ...
.
The party walked around the bay and past the site of present-day
Arcata, had a Christmas meal of elk meat near the
Elk River, and passed through present-day
Eureka on 26 December.
They reached the bay at a point which would later be both the location of
Fort Humboldt

and the townsite of
Bucksport, named after David A. Buck, the discoverer of the bay.
Three days later, they came upon and named the
Eel River, the "Eel" in the name being a misnomer for the
Pacific lamprey
The Pacific lamprey (''Entosphenus tridentatus'') is an anadromous parasitic lamprey from the Pacific Coast of North America and Asia. It is a member of the Petromyzontidae family. The Pacific lamprey is also known as the three-tooth lamprey and ...
which local Indians had caught and shared with the party at about where the
Van Duzen River, named after James Van Duzen, joins the Eel.
Shortly thereafter, the party argued again about the best way to get back to San Francisco.
About from the coast on the Eel River, the group split in two: Seabring, Buck, Wilson and Wood followed the Eel River, while Gregg, Van Duzen, Southard and Truesdale went to the coast.
L.K. Wood was permanently crippled by a

while stuck in a snow-bound camp.
His fellow travelers packed him on a horse and traveled along the South Fork of the Eel southward. When they arrived at
Santa Rosa, news of their discovery spread.
Gregg's group fared badly. Wood wrote:
They attempted to follow along the mountain near the coast, but were very slow in their progress on account of the snow on the high ridges. Finding the country much broken along the coast, making it continually necessary to cross abrupt points, and deep gulches and canyons, after struggling along for several days, they concluded to abandon that route and strike easterly toward the Sacramento valley. Having very little ammunition, they all came nigh perishing from starvation, and, as Mr. Southard related to me, Dr. Gregg continued to grow weaker, from the time of our separation, until, one day, he fell from his horse and died in a few hours without speaking—died from starvation—he had had no meat for several days, had been living entirely upon acorns and herbs. They dug a hole with sticks and put him under ground, then carried rock and piled upon his grave to keep animals from digging him up. They got through to the Sacramento valley

. Thus ended our expedition.
Southard's story of burying Gregg after his death may not be the whole truth. Other reports say he died on February 25 near Clear Lake, California, of poor health and the hardships of his journey,
while another casts doubt on the story that his companions buried him, instead suggesting he survived at least briefly at an Indian village.
In any case, his papers, instruments, and specimens were lost.
Legacy
Gregg's 1849–1850 expedition has been credited with the rediscovery of
Humboldt Bay

by land, which resulted in its settlement.
The Gregg party's trip triggered an 1850 expedition by Colonel Redick McKee to create treaties with Northern California Indians, which were never ratified.
About eighty plant names were originally assigned to honor Gregg; as of 2002, 47 Mexican and Southwestern plant species bear the specific epithet '.
Gregg's portrait, painted by
Herndon Davis between 1950 and 1962, is in the collection of the
Palace of the Governors, a New Mexico history museum.
