Since August, investigators in Mariposa County have dumped algae-filled water, long-lost mines known to emit toxic gases, and search for evidence of lightning strikes and toxic vegetation, all in order to determine the cause of youth. The mysterious death of the family.
However, according to a 77-page report obtained by the San Francisco Chronicle, investigators revealed on Friday that high temperatures, harsh terrain, and lack of shade and water eventually led to their deaths.
Mariposa County Sheriff Jeremy Briese held a press conference in October to announce that the couple and their daughter had died of hyperthermia and possible dehydration.
A family in Northern California was hiking on a remote trail near the Merced River in the Sierra National Forest. They were found dead on August 17 after a family friend reported them missing.

They have an 85-ounce Camelbak water bag, which is empty. Briese said that they have no other water containers.
Relatives said in a statement: "The loss of a family member is a pain that cannot be expressed in words."
"When this pain is suppressed by a lack of understanding of their deaths, the question of where, why, when and how to fill the emptiness, day and night."
They thanked the Sheriff’s Office for “really putting in extra effort” while trying to find answers.
"Some questions have already been answered, and we will use it to help us solve this problem.
"No matter where we go, no matter what we do, they will be with us.
"In the future, when we sit under a tree and listen to the wind blowing under the branches, we will think of them and we will remember them."
The body of a family of three and their pet was found on the Savage Lundy Trail 1.6 miles from the truck they parked
Briese says dehydration can cause dizziness and eventually death.
Hyperthermia is an abnormally high body temperature caused by a malfunction of the body temperature regulation mechanism.
The cause of death of this family’s dog has not been determined, but I believe this dog also suffers from high temperature related problems.
He said: "Our message to the hiking community is, please consider aquifers and geographical factors."
The deaths of Gerrish and Chung puzzled investigators for months

'Ready. The community is resilient, the community is safe, but due to the weather, this is an unfortunate and tragic incident.
The couple was described by friends as experienced hikers, but relatively newcomers to the area.
Briese said they may not realize how fast the terrain temperature is rising.
He said that when they started hiking, the temperature was in the mid-1970s; when they walked less than two miles, it was over 90.
Mariposa County Sheriff’s investigators collaborated with toxicologists, environmental experts, the FBI, and other experts.
They have ruled out causes related to guns or any other weapons, lightning strikes, carbon monoxide, carbon dioxide, cyanide exposure, illegal drugs, alcohol or suicide.
Briese said that when the family was found, there was "no obvious cause of death."
He said that it is well known that there are landmines in the area and the police are worried about possible environmental hazards.
The original theory was that they might be poisoned by toxic substances in the water.
Poisonous algae blooms were found about 12 miles downstream from where Grish and his family were found dead, prompting the Bureau of Land Management to close hiking trails and campsites along the Merced River earlier this month and open them to the public .
After water samples from the river tested positive for toxic algae, the authorities closed the 28-mile waterway between the towns of Brisborg and Bagby.
Briese said Thursday that they used six independent laboratories to test water.
"Water was confirmed to be positive for Anatoxin-A," Briese said.
Anatoxin-A is a natural toxin derived from blue-green algae, also known as rapid death factor (VFDF).
"There is no evidence that this family has ingested this toxin," he said.

Two days later, the search and rescue team found the parents, their one-year-old daughter and their dog Oski on the road.
Investigators previously revealed that Gerrish was studying the Hites Cove hike on the mobile app the day before the family embarked on their doomed journey.
The detectives believed that they had completed most of the work of a challenging 8.5-mile loop, which included driving 5 miles along a steep slope with little shade when the temperature reached 109 degrees, and then they died on the hiking trail. It was about 1.6 miles from their truck, which stopped at the beginning of the Hites Cove trail.
At 11pm on August 16, someone reported missing persons. About three hours later, the Mariposa County Sheriff’s deputy found their truck at the beginning of the trail at the end of Hites Cove Road.
