Cenozoic EraQuaternary Period

Ice Ages Focus

Jo’s Journeys wants you to take a trip back in time to…

Page 3: The Snowball Earth!

Travel back in time with us to a period that began 2.588 million years ago and continues to the present day…

A time when glacial periods had a great effect on our Earth (mostly in

the northern hemisphere)…

And a time when there were warm, even tropical inter-glacial periods.

Page 4: The Snowball Earth!

Ice Ages affect climates all over!

Ice, Snow (Precipitation)

Water Freezing & Thawing

Glaciations!

Page 7: The Snowball Earth!

So what causes Ice Ages?

Page 8: The Snowball Earth!

Possible reasons for Ice Ages:

Fainter early sunBiological changes

Variations in Earth’s orbit

There is evidence of more than 4 major glacial events and up to 40 smaller glaciations during the Quaternary Period – each lasting about 100,000 years.

Page 9: The Snowball Earth!
Page 10: The Snowball Earth!

Glacial intrusion on

North America

stretches down to

around 40 degrees latitude.

Page 11: The Snowball Earth!

The good news is…

there should be no fear of moving too far due to Continental Drift.

The continents have moved less than 100 km during this period.

Page 12: The Snowball Earth!

Wanna go to the Great Lakes region when you travel back?

Page 13: The Snowball Earth!

Here’s what they are like during this time period.

Page 14: The Snowball Earth!

So what do we know?

• During this period there is flooding, freezing & thawing ice, rising and falling seas, land bridges that form and disappear, lakes and bays form.

• Lots of activity happens during this period.

Wouldn’t you like to say youwitnessed it first hand?

Page 15: The Snowball Earth!

Global warming back then?

Page 16: The Snowball Earth!

• Coniferous & deciduous trees• Bushes and shrubs• Flowering Plants (angiosperms)• Ferns• Grasses• Mosses, liverworts, and hornworts

Take in the sights and smells of our “Continental Gardens” where

you will find (based on your vacation location):

Page 17: The Snowball Earth!

Flowering Plants help insects flourish because of their

nectar.

Page 18: The Snowball Earth!

See the megafauna

up close and

personal!

Megafauna are massive mammals that roam during this period – becoming extinct as the last Ice Age ends.Mammals during this period are larger and grew thicker coats to help them survive.Though very large, most of these large mammals are plant-eaters that feed on shrubs & grasses on the edges of the ice sheets.

These massive animals will become extinct as the climate warms. (It is also believed that humans may have over-hunted them.)

Page 19: The Snowball Earth!

Giant ground

sloths as large as elephant

s!

Page 20: The Snowball Earth!

Mastodons & woolly mammoths are some of the massive mammals around

during this time.

Page 21: The Snowball Earth!

Let’s not forget the presence of the giant

woolly rhinos!

Page 22: The Snowball Earth!

Are humans to blame for

the extinction

of the woolly

mammoths?

Page 23: The Snowball Earth!

Other animals you may encounter on land are:

• Bison• Oxen• Cave bears• Saber-toothed cats• Some birds are over 7 feet tall!• Beavers that are over 7 feet long!• Elephants• Modern rhinoceroses• Hippos• Modern birds• Insects

Page 24: The Snowball Earth!

Should you SCUBA dive to take in the underwater sights, you may

see the following in Earth’s seas…• Whales• Giant sharks• Otters• Seals• Giant fish• Modern fish• Squid• Crustaceans• Mollusks• Urchins• Plankton• Coral

Page 25: The Snowball Earth!

Let’s not forget, the Quaternary Period is also called, “Age of

Humans.”• Homo erectus appeared in Africa

during the Cenozoic Era at the start of this period.

• They eventually develop bigger brains and more intelligence. (This means they can think and solve problems!)

• Modern humans spread out to Europe, Asia and then on to Australia and the Americas.

• The future of our planet will be greatly affected by the Age of Humans!

Rising & Falling Water Levels

Massive Mammals

There is a limited supply of plant material in areas affected by glaciations. This trip is not recommended for vegetarians.

AccommodationsTravel

accommodations will be made by “Ice

Walkers.”

We’ll show you the way

to get there today!

Page 29: The Snowball Earth!

You will be staying in our exclusive “Ice House Hotel” designed with your needs in

mind.

Page 30: The Snowball Earth!

An elegant reception desk…

Page 31: The Snowball Earth!

All natural furnishings made from the purest frozen water

on Earth…

Page 32: The Snowball Earth!

And shelter from the wind, weather, and predators.

Page 33: The Snowball Earth!

Should you choose to stay longer and notice the ice beginning to thaw all around you, you may

need to stay in one of our hand-made huts.

Yes, I said “hand-made.”

Our huts are made of sturdy mammoth tusks, warm woolly fur, and are guaranteed to protect you

from the outside cold.

Friendly locals will welcome you to their frozen villages.
